ABSTRACT
Sometimes in statistics, the data under study are related to three or more variables, that is, information related to three or more variables is collected from each and every individual of the population or the sample. From such data, it may be of interest to find out whether there is any relation of one variable with all other variables of the data or is it possible to find the value of any one variable on the basis of the data if the values of all other variables are known. Multiple correlation and multiple regression analysis are the answer to the above questions.
