AP Statistics Summative Project

AP Statistics Summative Project Make hypotheses about a situation of interest. Collect data about this topic. Collect from two different but related populations that are generally normally distributed. Sample size must be at least 20. Use two types of data collection. Use two types of sampling. Discuss possible bias and how it can be avoided. Make a frequency distribution table. Make an appropriate display table indicating the mean. Make a display using quartiles. State a null and alternative hypothesis about each population independently. Perform the necessary steps to test the original claim. State a null and alternative hypothesis for a comparison between the two populations or two new populations of your choosing. Perform the steps to test this claim as a linear correlation, linear regression, or any two-variable test. Present your findings including the rationale behind all the choices made in either an oral performance or a descriptive essay.

1) Type of data (5 points) a) large vs small b) nominal, ordinal, ratio, interval 2) Method of data collection (5 points) a) must have two types b) why each type was chosen 3) Type of sampling (5 points) a) must have two types b) why each type was chosen 4) Possible bias (why and how to avoid it) (5 points) 5) Frequency distribution (at least 1 total) (10 points) a) class breaks to create normal distribution b) frequency 6) Graphical display (10 points) a) at least one type that shows mean and shape b) at least one type that shows median and quartiles Normal distributions (one large, one small; mean or proportion) 7) Null and alternative hypotheses for each test (20 points) a) type of hypothesis testing and why: large vs. small, mean vs. proportion, tails b) steps for performing the test and conclusion 8) Comparison of two populations (correlation, regression, independence, etc.) (20 points) a) type of hypothesis testing, hypotheses, and why: large vs. small, mean vs. proportion, tails b) steps for performing the test and conclusion 9) Presentation (Formal write-up or oral description) (20 points)
