The document contains questions about mean, median, and standard deviation calculations for sets of test scores. It asks the reader to calculate the mean of a set as the total sum of values minus the lowest value divided by the number of values. It also contains possible answer choices for comparing the medians of two sets of test scores and lists a set of algebra test scores to calculate the standard deviation for. Several PDF attachments related to math concepts are also included.
