Course Description for MATH 1342: A first course in statistics for students in business; nursing; allied health; or the social, physical, or behavioral sciences; or for any student requiring knowledge of the fundamental procedures for data organization and analysis. Topics include frequency distributions, graphing, measures of location and variation, the binomial and normal distributions, z-scores, t-test, chi-square test, F-test, hypothesis testing, analysis of variance, regression, and correlation. Skills: S Prerequisite: For sections of MATH 1342 paired with MATD 0166, the prerequisite is MATD 0365 and co-enrollment in the attached section of MATD 0166. Prerequisites: A satisfactory score on the ACC Mathematics Assessment Test. A second option is an appropriate secondary school course (Algebra II) and completion of any TSI-mandated mathematics remediation.

Note: Texas State University recently changed their Transfer Guide to show that MATH 1342 is no longer considered equivalent to their QMST 2333 (Quantitative Methods).   ACC’s BUSG 2371 is the correct equivalent to that course, which is needed for most majors in business.

Course Description for MATD 0166: The second in a two-semester course, to be paired with a designated MATH 1342 section. This course includes: describing real-world and quantitative relationships with equations, inequalities, graphs and tables; solving appropriate equations and inequalities and explaining how the results relate to original context; and appropriate use of approximate numbers instead of exact when required. Prerequisite: Math for Stat I and co-enrollment in MATH 1342.

Instructional Methodology: This course is taught in the classroom as a lecture/discussion course. The course will have numerous group learning activities which are mostly done in class.

MATH 1342 Course Rationale: Students will learn to

1. Determine the aspects of a question, if any, for which statistics can provide relevant information.

2. Analyze statistical studies, particularly regarding appropriate sampling and experimental design.

3. Select and use appropriate statistical analyses to get useful information from data.

4. Communicate knowledge using standard statistical language and also interpret it in non-technical language.

This course meets the Core Curriculum requirement in mathematics. It meets the requirement for an introductory statistics course for students in many majors such as business, health sciences, and social sciences.

Course Learning Outcomes:

Upon successful completion of this course, students will:

1. Explain the use of data collection and statistics as tools to reach reasonable conclusions.

2. Recognize, examine, and interpret the basic principles of describing and presenting data.

3. Compute and interpret empirical and theoretical probabilities.

4. Explain the role of probability in statistics.

5. Examine, analyze, and compare various sampling distributions for both discrete and continuous random variables.

6. Describe and compute confidence intervals.

7. Solve linear regression and correlation problems.

8. Perform hypothesis testing using statistical methods.

Learning Objectives for MATH 1342:

1. Interpret ideas of population versus sample, random variables, and techniques of descriptive statistics including frequency distributions, histograms, stem and leaf plots, boxplots, and scatterplots.

2. Calculate and interpret measures of central tendency and dispersion, including mean, median, standard deviation, and quartiles.

3. Apply the 68-95-99.7 rule to normal distributions and use the normal tables to answer questions about the proportion of scores in a certain range or find various percentiles.

4. Analyze relationships between two quantitative variables using correlation and linear regression. Analyze residual plots and determine how to handle outliers and influential points.

5. Analyze data presented in two-way and three-way tables to provide information about relationships between categorical variables, including understanding and interpreting situations to which Simpson's Paradox applies.

6. Apply ideas of appropriate sampling techniques and experimental design to data production.

7. Use the basic ideas of probability and apply them to statistics.

8. Use the sampling distributions of sample proportions and sample means to answer appropriate questions.

9. Estimate single means, difference of two means, single proportions and difference of two proportions using confidence intervals. Interpret the results.

10. Demonstrate skills in hypothesis testing for means and proportions, for single populations and comparison of two populations.

11. Demonstrate skills in hypothesis testing using the chi-squared test to compare several proportions and to test independence.

12. Demonstrate skills in inference for regression or ANOVA techniques.

Throughout the course, students will learn to do almost all the calculations by hand with a scientific calculator on small data sets and also students will learn to use a substantial statistical computer software package to do the statistical calculations quickly and on larger data sets. Some of the regression inference analyses will not be done by hand.

Learning Objectives for MATD 0166:

1. Use the language of mathematics to communicate ideas.

2. Demonstrate proficiency in conceptual understanding, strategic competence, and adaptive reasoning.

3. Solve quantitative problems and perform quantitative investigations in which they discover ideas and gain insights that develop questioning and solution-building skills.

4. Use mental strategies and technology accurately and appropriately.

Required Materials:

• Lessons from the Statway project (to be distributed during class)

• Online explanations and interactive materials and assessments from

• StatsPortal and The Basic Practice of Statistics, 5h ed., by David S. Moore

• Access to the data files for the textbooks from

•

Required Technology: (More information – )

1. Scientific calculator

2. Access to MINITAB computer software. You are not required to buy/rent this. Use it in the math labs, ICT labs, and the Learning Labs.

3. Internet access to use the supplements in StatsPortal and the materials at Internet access is provided in several computer labs at ACC.

Required Time:

You cannot learn math or statistics by listening to someone talk about it. You learn statistics by thinking about and working on statistics questions. And this takes time. If you allow yourself plenty of time to think about the material, you will find it much more interesting and enjoyable. A reasonable amount of time (for any college class, but especially for math) is three hours outside of class for every hour in class. You have made up your schedule this semester to include your classes at certain times every week. You should now include on that schedule certain regular hours for study—three hours of study for each hour you are in class. If you do not do this, you will not do as well in school as you are capable of, and you will find it more frustrating than it should be.

Course-specific support services:

ACC main campuses have Learning Labs which offer free first-come first-serve tutoring in various courses. Students should bring their text, course handouts, and notes when they come to the Learning Lab. The locations, contact information and hours of availability of the Learning Labs are available from

Not all math tutors can tutor statistics, so look at the schedule carefully to see when statistics tutors are available. Since the Statway materials are not as familiar to the tutors as the Moore textbook, be prepared to show your tutor your notebook with the materials and your access to If you locate a tutor who will help you more than once, we can provide your tutor access to and also to the electronic view of the student activities. Please ask the tutor to email your instructor to ask for the access.

Class Participation

This class is different in many ways from other math classes you may have been in. As we did last semester, you are going to interact with each other quite a bit and talk to each other about statistics. A lot of this work will be done in groups, and I will expect that you will contribute to the discussion of the problems that your group is working on.

I know that some of you do not like to talk in class and others of you like to talk a lot. So, we will be following a couple of easy rules. We give everyone a chance to talk. We respond to whatever anyone says with respect. We are concerned here about concepts that will help you learn statistics and I expect that students in this class will support each other in working together.

Part of your grade is on your classwork. Each day you will earn points for your work. During the last ten minutes of class I will review what students have been writing in their handouts for the day and record a grade. Students who are present and working steadily on the material with their groups will earn perfect grades on this for that day.

If you miss a class, you may earn up to 2 / 3 of the credit for that assignment by bringing it to show me that you have done it within a week after the class you missed. Hand it in (folded, with your name and a statement of what it is written on the outside) at the beginning of a class, submit it to the clerk in the NRG mailroom, or bring it to me to discuss during my office hours.

Homework

You will need a binder with at least five dividers to accumulate your homework papers.

Homework will have two components, written and online.

Written Homework:

Problems will be assigned from your Statway worksheets as well as the textbook. These will generally be due once a week, on Tuesday at the beginning of class. You must complete all problems assigned, even though not all will be graded for correctness.

You will need to show any calculations. Explanations are the important part of the problem. Copying out of the textbook answer key is PLAGIARISM. You need to write conclusions in your own words and these should match YOUR calculations (even if you couldn't get your calculations to come out exactly like those in the answer key). Your written homework must be written on blank paper, well-labeled and organized, with at least five blank lines between problems.

If a paper homework assignment is handed in late, there is a penalty of 15% for every class day it is late, up to three class days. It will not be accepted for a grade later than that.

After you receive it back, you are expected to compare your work with the answers and write comments in those five blank lines and keep those organized in your homework binder. Those comments are to help you when you study and you will earn some extra credit if you do these particularly well. I will look at these several times during the semester and give an extra credit grade on them at the end of the semester.

Online Homework:

You will be assigned online reading with interactive questions and applets to help you know if you are following along with the key ideas. You will be able to get instant feedback on these questions and be able to change your answers. There are also many hints.

At the end of each topic and module there is a Check Point assignment that will be graded. Your grade on your first attempt will be recorded, and the solutions will be available to you after that first attempt. To earn a higher grade, up to 85% on the assignment, submit a paper with, for each problem you missed on your first attempt, a discussion of each of the incorrect answers - how you would recognize an answer like that as incorrect on a new question on the same topic. This must be submitted no later than the beginning of the next class day after the deadline for the online assignment. It must be clearly labeled with the Module and Topic number, and the date submitted.

Online homework done late will receive a 15% penalty for every two days it is late, up to six days late. It will not be accepted for a grade later than that.

When you receive your paper with discussion back, you are required to put it in your binder in an organized fashion so that you can find it when you are reviewing that topic.

Extra credit on the homework: At the end of the semester, students are required to hand in their binder with the paper homework and their comments on each problem after reading the answer keys and their papers with discussion of the online homework. For a thorough job, a student may earn up to an additional 20% on the paper homework grade and the online homework grade, respectively, up to a maximum of 100% on each.

Exams

There will be three exams and a comprehensive final exam over all the material in both semesters of the course . Some exams will be held in class and some will be held in the Northridge Testing Center. If you prefer to take a Testing Center exam at another campus, you must send me an email one week prior to the start date for that exam with your request. (It takes time to send the exams to other campuses and get them processed.). Make sure to bring your ACC ID to the Testing Center and to ask for a test for MATD 0166, section 003, synonym 43256.

You are allowed to use a scientific calculator on any exam. You may bring your own or borrow one from the Testing Center. No graphing calculator is allowed on exams.

*There will be NO make-up exams. The final exam grade can be substituted for a lower exam grade on Exams 1-3, including a zero for a missed exam.*

Grading

Assessment and grading for the two courses, MATD 0166 and MATH 1342, is combined. Expect to earn the same letter grade in the two courses at the end of the semester.

In the Testing Center, we will identify this course by the MATD 0166 number, so that they will not mistakenly give you the exams for my other MATH 1342 classes, which cover the material in a different order.

| |Percentage | |Numerical grade |Letter grade |

| | | | | |

|In-class work |8% | |90% - 100% |A |

|Written homework |10% | |80% - 89% |B |

|Online homework |8% | |70% - 79% |C |

|Exam 1 |18% | |60% - 69% |D |

|Exam 2 |18% | |0% - 59% |F |

|Exam 3 |18% | | | |

|Final Exam |20% | | | |

|Total |100% | | | |

TSI Warning for students who are not TSI complete**

Students who are not TSI complete in math are not allowed to enroll in any course with a math skill requirement.

All students are required to be "continually in attendance" in order to remain enrolled in this course. If this MATD 0166 is the only developmental class you are enrolled in, and you withdraw yourself from this course or are withdrawn by your instructor, then:

a) You may be withdrawn from courses that you should not be enrolled in, such as any class with a math skill requirement.

b) You will have a hold placed on your registration for the following semester. The Hold will require that you register for the next semester in person with an advisor or counselor and that you work with the Developmental Math Advisor during that semester.

c) You will continue to face more serious consequences, up to being restricted to only registering for developmental courses, until you complete the required developmental math course or satisfy the TSI requirement in another way.

More information can be found at .

** If you are unsure whether or not this warning applies to you, see an ACC advisor immediately.

Importance of Completing Developmental Course Requirements

The first steps to achieving any college academic goal are completing developmental course requirements and TSI requirements. The first priority for students who are required to take developmental courses must be the developmental courses. TSI rules state that students are allowed to take college credit courses, if they are fulfilling their developmental requirements. Because successful completion of dev courses is so important, ACC will intervene with any student who is not successfully completing developmental requirements. This intervention can mean a hold on records, requiring developmental lab classes, working with the Dev Math Advisor, and monitoring during the semester.

Additional information about ACC's mathematics curriculum and faculty is available on the Internet at

Attendance/Class Participation: Regular and punctual class and laboratory attendance is expected of all students. If attendance or compliance with other course policies is unsatisfactory, the instructor may withdraw students from the class. In this class, missing more than 10% of the class time over the semester is considered unsatisfactory. That is approximately four classes of a class which meets two days a week in the 16-week semester.

Withdrawal Policy: It is the responsibility of each student to ensure that his or her name is removed from the roll should he or she decide to withdraw from the class. The instructor does, however, reserve the right to drop a student should he or she feel it is necessary. If a student decides to withdraw, he or she should also verify that the withdrawal is submitted before the Final Withdrawal Date. The student is also strongly encouraged to retain their copy of the withdrawal form for their records.

This semester is Spring 2012 and the Final Withdrawal Date for this class is April 23, 2012.



Students who enroll for the third or subsequent time in a course taken since Fall 2002 may be charged a higher tuition rate for that course.

State law permits students to withdraw from no more than six courses during their entire undergraduate career at Texas public colleges or universities. With certain exceptions, all course withdrawals automatically count towards this limit. Details regarding this policy can be found in the ACC college catalog.

Reinstatement Policy: In order to be re-instated in this class after a withdrawal, the student must be caught up with all the classwork, online and written homework, and be passing at the time of reinstatement. The deadline for reinstatement is the same as the deadline for a withdrawal.

Incomplete Grades: Incomplete grades will be given only in very rare circumstances. Generally, to receive a grade of “I”, a student must have taken all examinations, be passing, and after the last date to withdraw, have a personal tragedy occur which prevents course completion. An incomplete grade cannot be carried beyond the established date in the following semester. The completion date is determined by the instructor but may not be later than the final deadline for withdrawal in the subsequent semester.

Statement on Scholastic Dishonesty: A student attending ACC assumes responsibility for conduct compatible with the mission of the college as an educational institution. Students have the responsibility to submit coursework that is the result of their own thought, research, or self-expression. Students must follow all instructions given by faculty or designated college representatives when taking examinations, placement assessments, tests, quizzes, and evaluations. Actions constituting scholastic dishonesty include, but are not limited to, plagiarism, cheating, fabrication, collusion, and falsifying documents. Penalties for scholastic dishonesty will depend upon the nature of the violation and may range from lowering a grade on one assignment to an “F” in the course and/or expulsion from the college. See the Student Standards of Conduct and Disciplinary Process and other policies at

Student Rights and Responsibilities: Students at the college have the rights accorded by the U.S. Constitution to freedom of speech, peaceful assembly, petition, and association. These rights carry with them the responsibility to accord the same rights to others in the college community and not to interfere with or disrupt the educational process. Opportunity for students to examine and question pertinent data and assumptions of a given discipline, guided by the evidence of scholarly research, is appropriate in a learning environment. This concept is accompanied by an equally demanding concept of responsibility on the part of the student. As willing partners in learning, students must comply with college rules and procedures.

Statement on Students with Disabilities: Each ACC campus offers support services for students with documented disabilities. Students with disabilities who need classroom, academic or other accommodations must request them through the Office for Students with Disabilities (OSD). Students are encouraged to request accommodations when they register for courses or at least three weeks before the start of the semester, otherwise the provision of accommodations may be delayed.

Students who have received approval for accommodations from OSD for this course must provide the instructor with the ‘Notice of Approved Accommodations’ from OSD before accommodations will be provided. Arrangements for academic accommodations can only be made after the instructor receives the ‘Notice of Approved Accommodations’ from the student.

Students with approved accommodations are encouraged to submit the ‘Notice of Approved Accommodations’ to the instructor at the beginning of the semester because a reasonable amount of time may be needed to prepare and arrange for the accommodations. Additional information about the Office for Students with Disabilities is available at

Safety Statement: Austin Community College is committed to providing a safe and healthy environment for study and work. You are expected to learn and comply with ACC environmental, health and safety procedures and agree to follow ACC safety policies. Additional information on these can be found at . Because some health and safety circumstances are beyond our control, we ask that you become familiar with the Emergency Procedures poster and Campus Safety Plan map in each classroom. Additional information about emergency procedures and how to sign up for ACC Emergency Alerts to be notified in the event of a serious emergency can be found at .

You are expected to conduct yourself professionally with respect and courtesy to all. Anyone who thoughtlessly or intentionally jeopardizes the health or safety of another individual will be immediately dismissed from the day’s activity, may be withdrawn from the class, and/or barred from attending future activities.

Use of ACC email: All College e-mail communication to students will be sent solely to the student’s ACCmail account, with the expectation that such communications will be read in a timely fashion. ACC will send important information and will notify you of any college related emergencies using this account. Students should only expect to receive email communication from their instructor using this account. Likewise, students should use their ACCmail account when communicating with instructors and staff. Instructions for activating an ACCmail account can be found at .

Testing Center Policy: Under certain circumstances, an instructor may have students take an examination in a testing center. Students using the Academic Testing Center must govern themselves according to the Student Guide for Use of ACC Testing Centers and should read the entire guide before going to take the exam. To request an exam, one must have:

1. ACC Photo ID

2. Course Abbreviation (e.g. MATD)

3. Course Number (e.g. 0166)

4. Course Synonym (e.g. 43256)

5. Course Section (e.g., 003)

6. Instructor's Name (e.g., Parker, Mary)

Do NOT bring cell phones to the Testing Center. Having your cell phone in the testing room, regardless of whether it is on or off, will revoke your testing privileges for the remainder of the semester. ACC Testing Center policies can be found at

Student and Instructional Services: ACC strives to provide exemplary support to its students and offers a broad variety of opportunities and services. Information on these services and support systems is available at:

Links to many student services and other information can be found at:

ACC Learning Labs provide free tutoring services to all ACC students currently enrolled in the course to be tutored. The tutor schedule for each Learning Lab may be found at:

For help setting up your ACCeID, ACC Gmail, or ACC Blackboard, see a Learning Lab Technician at any ACC Learning Lab.

Calendar: Schedule changes may occur during the semester. The instructor will announce schedule changes in class.
