How does effect size relate to instrument sensitivity?

Question

Quizplus · Accepted Answer

Effect size is a measure of the strength of the relationship between two variables or the magnitude of a difference between groups. A sensitive instrument can detect small changes or differences, which means it does not require a large effect size to identify a difference. Conversely, if an instrument is not very sensitive, it will require a larger effect size to detect a difference, making choice B correct. Choices A, C, and D confuse the concept of effect size with the characteristics of the instrument itself.
