I would like to know how to determine the y and x factors needed to compute a multiple regression program based on the data supplied with this request. The solution here on Bartleby has broken images and has no assistance. I have learned how to run the program in Excel however, I am not sure which columns are needed in the analysis. The question simply states - estimate the demand for soft drinks using a multiple regression program available on your computer. Help? Thanks!

Correlation

Correlation defines a relationship between two independent variables. It tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.

Linear Correlation

A correlation is used to determine the relationships between numerical and categorical variables. In other words, it is an indicator of how things are connected to one another. The correlation analysis is the study of how variables are related. 

Regression Analysis

Regression analysis is a statistical method in which it estimates the relationship between a dependent variable and one or more independent variable. In simple terms dependent variable is called as outcome variable and independent variable is called as predictors. Regression analysis is one of the methods to find the trends in data. The independent variable used in Regression analysis is named Predictor variable. It offers data of an associated dependent variable regarding a particular outcome.
