Q1) In the extensive study involving thousands of British children, Arden & Plomin (2006) found considerably higher variance in intelligence scores for males than for females. Following are hypothetical data similar to results obtained in study. Note that scores are not regular IQ scores, but have been standardized so that whole sample has mean of M = 10 and standard deviation of s = 2.
a) Compute mean and standard deviation for sample of N = 8 females and sample of N = 8 for males.
b) Based on means and standard deviations, explain differences in intelligence scores for males and females.
Scores are as follows:
FEMALE
MALE
9
8
11
10
13
12
6
14
Just get the mean standard deviation for both males and females. Then compare standard deviations in part b.
