Assuming the same number of people is used in both analyses, would the independent samples t test or the paired samples t test be more likely to yield statistically significant results? Why?
What will be an ideal response?
Ans: The paired samples t test is more likely to yield statistically significant results because there will be more observations in each “group” being compared, thus giving us more statistical power and increasing the likelihood of rejecting the null hypothesis.
