'. The Cambridge Study in Delinquent Development was undertaken in north London (U.K.) to investigate the links between criminal behavior in young men and the socioeconomic factors i. Mehl et al. (2007) wired 396 volunteers with electronically activated recorders that allowed of their upbringing (Farrington 1994). A cohort of 395 boys was followed for about 20 years, starting at the age of 8 or 9. All of the boys attended six schools located near the research office. The following table shows the total number of criminal convictions by the boys between the start and end of the study. the researchers to calculate the number of words each individual spoke, on average, per 17- Number of convictions Frequency hour waking day. They found that the mean number of words spoken was only slightly 265 higher for the 210 women (16,215 words) than for the 186 men (15,669) in the sample. The 49 frequency distribution of the number of words spoken by all individuals of each sex is shown 21 in the accompanying graphs (modified from Mehl et al. 2007). 19 VOUTAWNY O 10 50 Go to page 918 10 Men 40- 2 N 30 Frequency 20 10 50 Women 40- 30 - NHWAAND Frequency 20 - 10 - 13 0 - 14 0 16,000 32,000 48,000 Total:395 Number of words per 17-hour day Whitlock et al., The Analysis of Biological Data, Ze, this? 2015 W.
