    This document contains the results of several statistical t-tests comparing the means of two samples. The first t-test found a statistically significant difference between the means of Variable 1 (mean=246) and Variable 2 (mean=141). The second t-test found a statistically significant difference between the means of samples measuring two different variables (means of 79.4444 and 68.125 respectively). The third t-test also found a statistically significant difference between the means of two samples (means of 6.5 and 9.125 respectively).
