Question

I was curious about the whether or not watching the weekly lecture had an impact on the grade students got on the assignment. It was my hypothesis watching the video would have a positive impact on assignment scores (i.e., that students who watch the video would have higher scores than those who don't) Here's the raw data for our class' Theory Essay Assignment: StudentScore Minutes Watched 5.25 9.38 21 21 22.13 22.13 23.25 23.35 24.38 25.5 25.5 25.5 26.63 26.63 27.5 27.75 27.75 27.75 28.88 28.88 27 0 32 21 13 26 67 32 56 Ul 38

Explanation / Answer

Since the p-value is smaller than significance level(0.05) we will reject the null hypothesis which in this case is that there is no positive impact on assignment grade due to watching the video.

Hence the conclusion based on evidence is that there is a positive impact of watching the video on assignment grade.

Since there is a positive impact the students should watch the video.
