UWO Descriptive Statistics for The Average Donation per Donor SPSS Software Analysis
Question Description
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.
