PSY 223 PSY223 Milestone 2-Research Question & Proposed Test- Snhu

A follow-up question post results may also include: what are the proposed determinants that enhanced the confidence levels between the two groups? To test the hypothesis, a two-sample t-test would be best for the given scenario. This statistical procedure aims to determine whether the means of two independent groups differ by calculating the range of values that generally includes the difference between the population means. This test aims to calculate a confidence interval by inducing a hypothesis of the difference between the two population means when standard deviations are unknown. It is based on the T-distribution, and for small samples, it tends to work better if the data is drawn from distributions that are close to or completely normal. Moreover, to achieve a two-sample t-test, the two populations or groups must be independent. This test works well in cases when the assumption of normality is violated, but only if the underlying distribution isn’t extremely skewed.
