Range of Data: 85 Mean: 8.61 Median: 4 Mode: 0

__Best Average__: Median. __Why?__ A couple reasons: 1. 10/20 of the responders score 4 or less – most score zero. 2. The score of 84 drastically sways the data to a higher average. Pull that out and the new mean goes to 4.1 – which is only a 10th away from our median. So, the median (in this case) is the best average.

__What’s the best average to use:__ There is no one right answer to this question. It depends on your data and what you’re trying to do with it. Each situation needs to be looked at individually before the appropriate average can be determined.

We used an unpaired test because we had a control and treatment group.

Comments: Tried doing this out with paper pencil, but got frustrated when we tried figure the variance for group B. Glad to find the program when we did – saved us a bunch of time.
