UNIT 7 STATISTICS PROJECT Instructions

Over the following week you will complete a statistics project. Each day you will complete another section. On the final day, you will compile all the data collected and analyzed onto a poster board.

Task 1

You will select a topic from the list of available project ideas. Each student in your class will have a different project. You will then use that topic to write a survey question that can be asked in your sample to get the results necessary to complete the tasks of this project. Create a tally sheet that indicates your question and a column showing the results of each person in your sample. Your sample size must be a minimum of 50 people, and your tally sheet must include labels and units. You will begin collecting data from your present math class.

All data should be collected by the time your class meets again on "Day 2."

Task 2

Part A ? You will tabulate (organize using a table) your data results from your sample of 50 or more.

Part B ? These results should then be presented in a stem and left plot. An example is given below.

Rewrite by putting the data in order

Part C ? Using the stem and leaf plot data and your sample data results, you will find the statistical distribution. Follow the sample below. In addition, include the range and any outliers (if any).

Range

Find the difference between the maximum and minimum of the data.

Outlier

Find the data point that is clearly separated from the rest of the data.

Task 3

P o s te r b o a r d s h o u ld b e b r o u g h t to s c h o o l.

Create a circle/pie graph of your results with appropriate colors and labels/units. Use proper headings and number formats. An example is given below.

Task 4

Part A ? Create a histogram or bar graph. Use appropriate intervals and proper chart formats with headings and labels (including units).

An example is given below.

Part B ? Create a box--and--whisker plot of your results. Be sure to include all parts of the five--number summary and all appropriate labels. An example is given below.

(Median of 1st half of data) (Median of 2nd half of data)

Task 5

Part A ? Write a minimum of a five--sentence summary of your findings. Use the following questions to guide you in writing this summary.

1. What conclusion can you make based on the results you collected? 2. Do you think there were any variables (reasons) that might have made your results what they were? 3. Based on the survey/data sampling you collected, do you believe it is a good representation of the

students at LHS? 4. Based on the survey/data sampling you collected, which method(s) of representation best fits your

data and why? 5. After completing this assignment/project, are there any areas of statistics that are still not clear to

you?

Be as specific as possible.

Part B ? Organize all components on a poster board for your final project grade.

Your poster board should include the following:

? The survey question (as the title) ? Your initial table with the data results you collected ? A list of the five statistical measures ? All four charts/graphs that were created ? Your project summary
