This test comes in 3 different versions. Forms A and B are equal in difficulty. Form C assesses the same concepts as the other forms, but it is intended for students with IEP accommodations. Form C is roughly half the length with slightly easier questions. The following topics are assessed on all 3 forms: identifying populations and samples, distinguishing between parameters and statistics, determining methods of data collection (Experiment, observational study, or survey), determining if data is qualitative or quantitative, finding measures of center (mean, median, and mode), constructing box-and-whisker plots, finding range and interquartile range, finding z-scores, interpreting standard deviation in normal distributions, finding sample proportions, finding margin of error, and finding sample size. An answer key is included for each form of the test.
