In looking at a scatterplot of interrater reliability, why would a researcher want to see all the dots close to the line of agreement?
A)Because it indicates a positive relationship
B)Because it indicates that the researcher's two research assistants/raters are making similar measurements

If the dots are close to the line of agreement, it indicates that the two research assistants/raters are making similar measurements. This is important for interrater reliability, which measures the degree of agreement between two or more raters. If the raters are making similar measurements, it increases the reliability and validity of the data collected. However, it does not necessarily indicate a positive relationship or high test-retest reliability.
