Jacqueline wanted to assess the reliability of ratings made of children's aggressive behavior so she had two students rate the degree of aggression displayed by each of 50 children while engaged in play. She then compared the ratings made by these two students and computed the degree of agreement between them. Jacqueline used what method of assessing reliability? Group of answer choices a. interobserver reliabilityb. interrater reliabilityc. internal consistencyd. reliability test-retest reliability

B. Inter - rater reliability.

Explanation:

Inter - rater reliability is a system of assessing the degree of consistency in two measurements gotten by different raters.

Due to human errors that could result from various individual differences, environmental factors, lack of presence of mind and not paying attention to details, there could be inconsistencies that might arise when two people are given the task of rating things.

Inter - rater reliability can be checked by;

1. Identifying how harmonious the ratings compiled by the two observers are, and,

2. Measuring (in percentage) the categories of data compiled by two raters. Of the 50 children, if the two raters marked 10 children to be in the same category, it would mean that there is 20% consistency.
