Hours of Play per Week
The mean of the number of hours played per week was 21.9, and the median was 20. Players under the age of 23 tend to play about 2 hours more each week than players over 22 (23.2 -vs- 21.2, p = .01, significant, but a trivial difference with this sample size). There were no gender differences.
A multiple regression analysis using age, gender, motivations and personality traits revealed that the motivation to socialize and find group affiliation were the best predictors of hours of play per week. Even though the contribution coefficients seem small, for comparison note that between the lowest and highest scoring players on the Social motivation is a difference of about 8.5 hours played per week (from 17.1 to 25.5 hours).
