Extracted text: 22. In an extensive study involving thousands of British children, Arden and Plomin (2006) found significantly higher variance in the intelligence scores for males than for females. Following age hypothetical data, similar to the results obtained in the study. Note that the scores are not regular 1Q scores but have been standardized so that the entire sabnple has a mean of M 10 and a standard deviation of s 2. a. Calculate the mean and the standard deviation for the sample of n 8 females and for the sample of n 8 males. b. Based on the means and the standard deviations, describe the differences in intelligence scores for males and females. Female Male 6 11 01 01 13 11 12 8. 9 01 14 6 11 6
