Question
1. The difference between y and ý is called a 2. A table between multiple independent variables and the dependent variable that shows all possible correlation coefficients is known as a matrix. 3. If there is a linear relationship between the dependent variable and the independent variables, a plot of the residuals will appear 4. In a regression model, dummy variables are used to describe (quantitative, qualitative) SUMMARY OUTPUT 9209724 R Square Adjusted R Square Standard Eror 0824220187 ANOVA 702349 11107047 1987949 1309496 59932E OR Residual 19 Total Pvalue Lower 95% 2308 206598 509841448 381 4386611 4 1199551 91 9694702 71.6464106 168 8039991 08303734 4.691767962 3337 910533 344 1616518 28.1278305S 145172296 Sharp Sony 930827133 035783509 798276-0 690370225 5. What is the sample size? 6. How many independent factors were evaluated? 7. Determine the Coefficient of Determination.Explanation / Answer
1). Residual
2) correlation matrix
3). Randomly Scattered.
4). Qualitative
5). Sample size = 23
6). Independent factors = 3
7). Coefficient of determination = 11107047/13094996
=0.84819
84.82% of variation in value is explained by the model.
