In a study of stress, researchers used a stress rating scale to compare two groups of participants.

Participants in Group A were a volunteer sample of people who attended a self-help group for people with stress.

Participants in Group B, the control group, were a volunteer sample of people who attended a community centre.

The researchers used an inferential statistical test to see if there was a significant difference in stress rating between the two groups.

Explain why a Mann-Whitney test is an appropriate choice of statistical test in this situation and a Spearman’s test is not.
