Use the dataset

1a: Create a new variable indicating “average donation per donor”. Report the descriptive statistics for this variable.

1b: Exclude the campaigns that raised less than $100 and more than $20,000. Report the descriptive statistics again and discuss why/how those changed (if they did).

2a: Run an independent samples t-test examining the differences in one of the linguistic variables based on whether they were posted on a weekend or not. Interpret the results in the written format.

2b: What is the difference between independent samples t-test and paired-sample t-test? Explain with an example outside of what is presented in the textbook and lecture video.

3a: Select cases from only three fundraising fields (e.g., medical, education, memorial) of your choice. It could be any three based on your curiosity and interest.

3b: Examine the differences between these three groups on: (i) donation amount, (ii) average donation per donor. Hint: Since you have three groups, you should use the post-hoc option on SPSS to provide you with pairwise comparisons.

3c: Ask for the bar graphs illustrating both effects.

3d: Based on the findings from 3b, interpret the results and discuss both the “overall” and “pairwise” differences. The overall effect is often called the “omnibus” effect.
