A study conducted to identify symptoms of anxious school-age children reported the following data (Test Scores Scales X SD): Withdrawn 67.4, 10.9; Somatic complaints 71.8, 10.2; Attention problems 62.7, 7.5; Anxiousness 68.2, 10.4; Social interaction problems 61.4, 11
1. On which scale did the children have the most variability in their scores?
1. Social interaction problems
2. Attention problems
3. Withdrawn
4. Somatic complaints
1
Rationale 1: The more the variability in scores, the greater the standard deviation. Therefore, the scale with the largest SD, social interaction problems, represents the scale with the most variability in scores.
Rationale 2: Attention problems have a lower SD, therefore, less variability in scores.
Rationale 3: Withdrawn has a lower SD, therefore, less variability in scores.
Rationale 4: Somatic complaints have a lower SD, therefore, less variability in scores.
Global Rationale:
