Week 2 Practice Worksheet

Prepare a written response to the following questions.

Chapter 3

1. For the following scores, find the mean, median, and the mode. Which would be the most appropriate measure for this data set? The mean would be the sum of all numbers which is

2+2+0+ 5+1+ 4+1+ 3+ 0+ 0+ 1+ 4+ 4+ 0+1+ 4+ 3+ 4+ 2+ 1=124. X(sum)/N=124/20. N=6.2.

The median would be the middle score, the sum of all numbers added together (124) and divided by (20)=6.2. This would be the middle score. The mode is the value in a data set that occurs most often or most frequently. 0,0,0,0,1,1,1,1,1,2,2,2,3,3,4,4,4,4,5. We learn in our chapter reading that The mode would be 1. It occurs most frequently. In sum,
