When conducting a hypothesis test for the difference between two means it’s essentially called a two sample t-test. According to Dr. Mirabella (2011, p. 5-2) states that, “In each case you can conduct a t-test for independent means to determine if a significant difference exists.” Furthermore, we’re conducting this test to see if there is an overlapping or if there is clearly a difference among the GPAs for men and women. In our case we are comparing the GPAs for a sample of men and a sample of women GPAs. Therefore, since we are trying to determine if there is a difference we would need to conduct the two-tailed directional test. As it’s defined as configuring if whether or not a difference exists in the two means (Mirabella, 2011). Even

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…
Some males could possibly believe that their counterparts did not fully understand the material and were not able to fully retain the information being taught. However, when in retrospect, the women GPAs were only slightly lower, but that could be attributed to various reasons such as their test-taking skills are not as strong as men, homework could be a slight issue with combining all the other responsibilities they currently have, or it could be they are not fully understanding what is required of them in the course. 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
