Regression

In simple regression, one _______ variable (X) is used to predict a __________ (Y)

An important feature of regression is that the ________ the correlation between 2 variables, the more accurate the prediction
higher

_____ indicated a perfect correlation.
r= 1.00

When there is a perfect correlation between two variables, we need only measure _____ to know the value of the other
one

The basic linear regression equation is:
Y' = a + bX
What is Y', a, b, X
 Y'= predicted value of variable Y
 a= intercept constant
 b=regression coeeficient
 X=actual value of variable X
