Comparing intelligence scores for males and females.

In an extensive study involving thousands of British children, Arden & Plomin (2006) found significantly higher variance in intelligence scores for males than for females. Following are hypothetical data similar to the results obtained in the study. Note that the scores are not regular IQ scores, but have been standardized so that the entire sample has a mean of M = 10 and standard deviation of s = 2.    

1.      a.      compute the mean and standard deviation for the sample of N = 8 females and the sample of N = 8 for males.

 

2.      b.      Based on the means and standard deviations, describe differences in intelligence scores for males and females.

The scores are as follows:

FEMALE

MALE

9

8

11

10

10

11

13

12

8

6

9

10

11

14

9

9

 Just obtain mean the standard deviation for both males and females. Then compare the standard deviations in part b.
