The value for SSresidual for regression can be obtained directly by measuring the difference between each predicted Y value (from the regression equation) and the actual Y value. Which of the following is an alternative method for obtaining SSresidual? Group of answer choices multiply SSX by (1 – r2) multiply SSY by (1 – r2) multiply SSY by r2 multiply SSX by r2
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.
