Question

two experimenters document the aggressive behaviours of children after watching either a violent or non - violent cartoon. after the observations, the two experimenters compare the number of observed acts of aggression that each of them documented. the two experimenters are checking for what type of reliability?
measurement consistency reliability
inter - rater reliability
alternate form reliability
test - retest reliability

which of the following correlation coefficients represents the strongest relationship between two variables?
-.25
+.19
+.43
-.47

Explanation:

• For the first question: Inter - rater reliability is about the agreement between different raters (here, the two experimenters) on the observed behaviors. Measurement consistency reliability is a more general term. Alternate form reliability is about different forms of a test. Test - retest reliability is about the same measure over time.
• For the second question: The strength of a correlation coefficient is determined by its absolute value. The absolute values of the given coefficients are \(| - 0.25|=0.25\), \(|+0.19| = 0.19\), \(|+0.43|=0.43\), \(|-0.47| = 0.47\). The larger the absolute value, the stronger the relationship.

Answer:

• First question: B. Inter - rater reliability
• Second question: D. - 0.47
