Regression analysis is:
a. used to predict change in one variable based on change in another.
b. dependent on a positive correlation coefficient.
c. dependent on low standard deviation in the data set.
d. used when there is a negative correlation coefficient; one variable regresses.

Regression analysis helps to predict the value of the dependent variable which changes when any one of independent variables varies, while other independent variables remain fixed.

Generally Regression analysis are classified in linear and non-linear regression.

Hence, the correct option is A.

Regression analysis is: a. used to predict change in one variable based on change in another. b. dependent on a positive correlation coefficient. c. dependent on low standard deviation in the data set. d. used when there is a negative correlation coefficient; one variable regresses.
