Question

Relationship and difference between simple,partial and multiple correlation

Answer 1

Partial correlation 

Partial correlation is a process in which we measure of the strength and also direction of a linear relationship between two continuous variables while controlling for the effect of one or more other continuous variables it is called 'covariates'  and also 'control' variables.in partial correlation between independent and dependent variables has not distinction.

Multiple correlation 

multiple correlation is the process in statistics, the coefficient of multiple correlation is the measure of how well a given variable can be predicted using a linear function of the set other variables. It is a correlation between the different variable's values and the best predictions that can be computed linearly from the predictive variables. The coefficient of multiple correlation takes the values between 0 and 1.  

Answer 2

SIMPLE, PARTIAL AND MULTIPLE CORRELATION. ... In multiple correlation three or more variables are studied simultaneously. Forexample, when one studies therelationship between the yield ofrice per acre and both the amountof rainfall and the amount offertilizers used, it is a problem of multiple correlation.
