PLEASE RATE! :) My Statistics students needed practice when they first learned how to calculate a t-statistic. I came up with this activity that requires students to work backwards using the t-statistic formula to either find the sample mean or the sample standard deviation.
Each student will have different numbers, but two of the cards will have the same sample mean and same sample standard deviation. Once the student solves for the missing statistic, they will walk around and find another student who has the same sample mean and same sample standard deviation as they have. In the past, this is how I have had students change partners. Once they "found their match", they sat together and worked together the rest of the period.
Each card will contain the t-statistic, population mean and sample size. The card will also have EITHER the sample mean OR the sample standard deviation.
