Algebra I Statistics Partner Project

Students will be working with a partner to design a statistics project that must accomplish the following:

I. Univariate Data

1. Choose a topic of interest from the datasets available in the Algebra I class links file. Ask a question about that topic and use the statistics to answer the question.

2. Determine whether your data is quantitative or qualitative, and whether your sample population is random or biased. If biased, explain why and suggest a method of getting a more random sample.

3. Investigate measures of center by making a stem and leaf plot. Determine the mean, median, and mode and explain which measure of center best represents the data.

4. Investigate measures of spread by making a box and whiskers plot. Identify the five key numbers (min, max, quartiles), the range, the interquartile range, and any outliers.

5. Make a histogram that shows the frequency distribution of the data. Discuss the spread, symmetry, and skewness of the bar graph. Describe any clustering of the data.

II Bivariate Data

1. Select two variables from one of the datasets available and determine their relationship. Ask a question about the relationship and use the statistics to answer the question.

2. Display the data in chart form using a spreadsheet.

3. Investigate the relationship between the two variables by making a scatterplot.

4. Describe any clustering of the data.

5. Describe the relationship of the data. Draw a best-fit line if appropriate, and find the equation of the best-fit line.

You will need to turn in the following:

1. A paper displaying all data, graphs, and discussions.

2. A poster to be shared with the class. The poster must display your univariate data and include some type of graph. Be creative by using pictures or other types of media if you desire.
