What type of study method does this represent and can the results be used to make generalizations about the population?Resources:Pearson Algebra 2 Common Core: Chapter 11 (Sections 11.1 – 11.5 & Section 11.8): pages 674 – 709 & pages 725 – 730Standards:CC.2.4.HS.B.4 – Recognize and evaluate random processes underlying statistical .2.4.HS.B.5 – Make inferences and justify conclusions based on sample surveys, experiments, and observational .2.4.HS.B.6 – Use the concepts of independence and conditional probability to interpret .2.4.HS.B.7 – Apply the rules of probability to compute probabilities of compound d events in a uniform probability model.A2.2.3.2.3A2.2.3.2.1A2.2.3.2.2Vocabulary:Bias- a systematic error introduced by a sampling method; Combination: any unordered set of r objects from a set of n objects. The number of combinations of n objects taken r at a time is nCr=n!r!n-r! ; Conditional Probability- the probability that event B will occur, given that event A has already occurred PAB=PA and BPA ; Contingency table- a frequency table that contains data from two different categories; Controlled Experiment- a sample is divided into two groups, one group receives “treatment” the other group (control group) does not receive treatment and then the two groups are compared; Convenience Sample- members of a population who are conveniently and ready available are chosen for a sample; Dependent Events- two events where the outcome of the first event does affect the probability of the second; Experimental Probability- the ratio of the number of times the event occurs to the total number of trials; Independent Events- two events where the outcome of the first event does not affect the probability of the second; Mutually Exclusive Events- When two events cannot happen at the same time (If two events are mutually exclusive then PA or B=PA+PB and PA and B=0); n factorialn!- for any positive integer n, n factorial is given by 1*2*3*…n-1*n; Observational study- members of a sample are observed in a way that they are not affected by the study; Permutation- an arrangement of items in a particular order. For n items arranged r at a time nPr=n!n-r!; Population- All the members of a set; Random Sample- members of a population are selected at random to be part of a sample, each member has an equally likely chance of being selected; Sample- a part of a population; Sample Space- the set of all possible outcomes in an experiment; Self-Selected Sample- members of a population that volunteer are selected for a sample; Simulation- a model that imitates one or more events; Survey- every member of a sample is asked a set of questions; Systematic Sample- members of a population are ordered then selected at regular intervals for a sample; Theoretical Probability- If a sample space has n equally likely outcomes, and an event A occurs in m of theses outcomes, then PA=mn Comments: Content: RegressionDuration: May (3 weeks)Essential Question:How can real world data be model by an equation?How can you make predictions based on data?Skill: Model data with linear functionsModel data with quadratic functionsModel data with polynomial functions (cubic and quartic)Model data with exponential and logarithmic functionsDetermine the appropriate type of regression model for a set of data.Use regression equations to make predictions Assessment:Given a set of data, run a linear regression on the graphing calculator. Use the regression equation to make predictions.Given a set of data, run a quadratic regression on the graphing calculator. Use the regression equation to make predictions.Given a set of data, run a cubic and quartic regression on the graphing calculator. Use the regression equation to make predictions.Given a set of data, run an exponential and logarithmic regression on the graphing calculator. Use the regression equation to make predictions.Given a scatterplot and/or a set of data, determine the regression type that best models the data. Use the correlation coefficient (r-value) to confirm your prediction.Resources:Pearson Algebra 2 Common Core: Section 2.5 (pages 92 – 99), Section 4.3 (pages 209 – 214), Section 5.8 (pages 331 – 338), Section 7.2 (pages 445 – 450), Section 7.3 Concept Bite (pages 459 & 460) “Bungee Barbie” Lab“Challenger Space Shuttle (O-ring)” LabStandards:CC.2.4.HS.B.2 – Summarize, represent, and interpret data on two categorical and quantitative variableCC.2.4.HS.B.3 – Analyze linear models to make interpretations based on the .2.1.HS.F.3 – Apply quantitative reasoning to choose and interpret units and scales in formulas, graphs and data 2.1.HS.F.5 – Choose a level of accuracy appropriate to limitations on measurement when reporting quantities.A2.2.3.1.2A2.2.3.1.1A2.2.3.1.2 A2.2.3.1.1 A2.2.3.1.2Vocabulary:Correlation Coefficient (r-value)- a statistical measure of the degree to which changes to the value of one variable predict change to the value of another, correlation coefficients are expressed as values between +1 and -1; Regression Equation- an equation that represents the relationship between two quantitative variable; Scatterplot- the graph of plotted points that shows a relationship between two sets of dataComments: ................
