Question

(a) What is meant by simple, partial and
multiple correlation?​

Answer 1

Answer:

1)Simple correlation is a measure used to determine the strength and the direction of the relationship between two variables, X and Y. A simple correlation coefficient can range from –1 to 1. However, maximum (or minimum) values of some simple correlations cannot reach unity (i.e., 1 or –1).

2)Partial correlation is a method used to describe the relationship between two variables whilst taking away the effects of another variable, or several other variables, on this relationship.

3)It is the correlation between the variable's values and the best predictions that can be computed linearly from the predictive variables. ... The coefficient of multiple correlation takes values between 0 and 1.
