RESEARCH DESIGN AND T TESTS: HOW ARE THEY CONNECTED?

Research Design and T-Tests Student Names Affiliation Course Number and Name Instructor Name Due Date Which is the research design used by the authors? Why did the authors use this t-test? Sanhueza et al.'s (2025) article employed a quasi-experimental research design together with non-randomized convenience sampling to assess the effect of a teacher training program on student learning outcomes at the Universidad Tecnológica Metropolitana of Chile. The researchers analyzed differences in students' grade point averages (GPA) between courses taught by trained and untrained teachers. The researchers used an independent samples t-test to evaluate whether the difference in mean GPA between students taught by trained instructors and those taught by untrained instructors across multiple semesters was statistically significant. Do you think it's the most appropriate choice? Why or why not? Did the authors display the data? In this case, the t-test was suitable because t-tests compare the means of two groups to ascertain any effect on the population (West, 2021). According to McClenaghan (2022), if the data had not been regularly distributed, different non-parametric tests, such as the Mann-Whitney U test,...
