Question 21

Study of Social Anxiety

In a study investigating social anxiety, researchers used a standardized social interaction rating scale to compare two groups of participants.

  • Group 1 consisted of a sample of individuals diagnosed with Social Anxiety Disorder (SAD) recruited from an online support forum.
  • Group 2 (the control group) consisted of a sample of individuals recruited via a public library notice board.

The researchers used an inferential statistical test to determine whether there was a significant difference in social interaction rating scores 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.
