Activity 8: Perform Survey Analysis
The goal of this week's activity is to practice inferential analysis using the course participation survey administered at the beginning of the quarter (preview).
You may complete this exercise individually, with team members, ad-hoc groups from class, or any combination of these. To receive credit, please post or reply to a post in the activity 8 discussion board on D2L. The post should include who was involved and a short summary of your experience. Share analysis results at your own discretion. Posts or replies should be done before noon Monday to ensure participation credit.
Class Demo
The in-class demonstration shows multiple ways to conduct these analyses:
- t-test comparing the 'effect' of section (in-class vs online) on preference for individual learning
- linear regression predicting synchronous preference (aggregate of in-person and zoom) based on preference for interactive learning
The data file and R code for these demonstration are reviewed in class.
Analysis for this exercises
For this exercise, conduct the following:
- t-test comparing the 'effect' of section (in-class vs online) on expected frequency for asynchronous group activity (AsyncActivity in the R code)
- linear regression predicting expected frequency for asynchronous group activity (AsyncActivity in the R code) based on preference for individual learning (IndivLearning)
Your posts may be brief. Consider focusing on your experience doing it and any qualitative interpretations on the results.
