Textbook Problem

A researcher conducts a study comparing two different treatments with a sample of *n* = 16 participants in each treatment. The study produced the following data:

Treatment 1: 6 7 11 4 19 17 2 5

9 13 6 23 11 4 6 1

Treatment 2: 10 9 6 6 1 11 8 6 3

- 2 11 1 12 7 10 9

**a.**Calculate the mean for each treatment. Based on the two means, which treatment produces the higher scores?**b.**Calculate the median for each treatment. Based on the two medians, which treatment produces the higher scores?**c.**Calculate the mode for each treatment. Based on the two modes, which treatment produces the higher scores?
