Regression
4. In simple regression, one _______ variable (X) is used to predict a __________ (Y)
• independent
• dependent
5. An important feature of regression is that the ________ the correlation between 2 variables, the more accurate the prediction
higher
6. _____ indicated a perfect correlation.
