Consider the following table: Source SS DF MS Test Statistic Regression 5720.255720.25 ?? Error 1111 504.32504.32 Total 11267.7711267.77 1616 Step 3 of 9 : Calculate the Mean Squared Regression. Round your answer to two decimal places, if necessary. Calculate the value of the test statistic How much of the variation in the dependent variable is explained by the regression? What proportion of the variation is explained by the regression? What is the estimated variance of the error terms? Round your answer to two decimal places, if necessary. : What is the total variability of the dependent variable? Round your answer to two decimal places, if necessary. : What is the variance of the dependent variable? Round your answer to two decimal places, if necessary.
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.
Consider the following table:
| Source | SS | DF | MS | Test Statistic |
|---|---|---|---|---|
| Regression | 5720.255720.25 | ?? | ||
| Error | 1111 | 504.32504.32 | ||
| Total | 11267.7711267.77 | 1616 |
Step 3 of 9 :
