Fill in the blanks. a. The F-statistic for a test of the utility of a multiple linear regression equation is obtained by dividing _____ by _____. b. The degrees of freedom for the F-statistic for a test of the utility of a multiple linear regression equation are ______ and ____. c. The test statistic for a t-test of the utility of a particular predictor variable in a multiple linear regression equation is obtained by dividing ______ by _______. d. The number of degrees of freedom for the test statistic of the utility of a particular predictor variable in a multiple linear regression equation is _______.
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.
