There is however no requirement that the two samples should be of equal size - often times they would be unequal though the odd case of equal size cannot be ruled out” (Independent Two-Sample Test, 2009, n.p.). Furthermore, There is some conditions that must be met prior to performing the two-sample t-test. The dependent variable is continuous (interval or ratio), the independent variable that is categorical and must contain two or more groups, and data should be normally distributed. To do a 2-sample t-test, the two populations must be independent; and therefore, the observations from the first sample must not have any connection or significance on the observations from the second …show more content…

The men are somewhat outshining the women, possibly, perhaps they are overall better performers and studious in providing detailed explanations in their homework. The men are not necessarily ranking higher because they are retaining information more effectively than women. Another possibility could be a result as to why the men have higher GPAs could result from the male participation in class is more prevalent than the females. The higher GPAs could also result from producing good quality work and making sure it is turned in on time and that it exceeds expectations. Primarily, I believe the females mean GPAs slightly lack due to they have a lot on their plates with factoring in school, work, home, and personal lifestyle behaviors that somewhat conflict with their studies at times. Furthermore, procrastination could play a vital role as to
