A researcher is interested in differences in cognitive function between older and younger women. She administers a 10 point cognitive test to two samples of women (younger and older). The following are the scores:

Younger Women: X= 8, 6 6, 7, 8, 7, 8, 8

Older Women: X= 7, 5, 8, 5, 7, 6, 8, 5

1. Compute the range, variance, and standard deviation for each group
2. Answer which group had more consistent (less variables) scores.
3. Rules:
4. USE TABLES TO COMPUTE the values
5. show work and formulas
