In a study performed on comfort food eating during times of stress, it was found that mean rated comfort food consumption level (on a scale from 1-20) for a group of students undertaking their exam period was 16. In comparison, a group of students who were not undertaking exams or examination preparation had a mean rated comfort food consumption level of 14. The pooled estimate of the population variance was 64. What is the estimated effect size (d) of the study?
