It is really helpful to start reading professional research articles to see how these concepts are used in actual study scenarios. Give it a try in the following article, where the researchers used the t-test to analyze the relationship between clinical simulation methodologies and student learning. Scherer, Y., Foltz-Ramos, K., Fabry, D., & Chao, Y. (2016). Evaluating simulation methodologies to determine best strategies to maximize student learning. Journal of Professional Nursing, 32(5), 349–357.

Look at Table 3 in the article. Was there a significant difference between the knowledge scores on the first posttest and the second posttest?
