Question
A researcher is examining the relationship between stress and productivity at work and wants to use a correlation coefficient . However, when the researcher plots the relationship between these two variables, he finds that productivity increases as stress increases to a moderate level and, from that point on, increases in stress are associated with a DECREASE in productivity. This results in a curved relationship. This data violates the assumption of:
Group of answer choices
related pairs
interval/ratio measurement
a linear relationship between X and Y
no outliers in either direction for either variable
