marks) Astudy was conducted to investigate the effectiveness of active learning in a university's introductory biology course. At the start of term, all students were given a pre- test. After the pre-test the students were split into two groups: one group was taught using traditional lectures (ni-110) and the other group was taught using a variety of active learning methods (n2-115). At the end of term all students were given a post-test. The data was analyzed using R. The variables in the analysis are: All pretest marks pretest postest pre.traditional pre.active post.traditional post.traditional All posttest marks Pretest marks for the students who were taught using traditional lectures Pretest marks for the students who were taught using active learning methods Posttest marks for the students who were taught using traditional lectures Posttest marks for the students who were taught using active learning methods > t.test (posttest,pretest) Welch Two Sample t-test p-value

Explanation / Answer

Here, since p-value is less than alpha, we conclude that the null hypothesis is rejected.

I.e.. There is a significant effect of active learning on the student marks.

Here, we assume that alpha is 0.10.
