Question

For which of the following measures would interrater reliability most likely be relevant? A measure of aggression where researchers watch children's interactions on a playground A measure of self-esteem where people respond to 10 items on a questionnaire A measure of brain activity that involves placing participants in an MRI machine A measure of body weight where people stand on a scale in a doctor's office

Answer 1

Answer: Option D

A measure can be considered valid until the measure is reliable. Health-o meter scale is a reliable, accurate,  and repeatable medical scale which is used to measure the weight of the people in the hospital or clinic.

This machine or scale is also used in the gym where the people want to measure the weight more actively.

Hence, option D is the most reliable and relevant source for the interrater reliability.
