3F)What is the coefficient of determination and what is it telling you about the relationship between these two variables?
In statistics coefficient of determination or R²(or r²), is a measure to assess the predicting ability of a model that is ability to explain or predict the outcome in the linear regression setting.
R² indicate the measure of variance in the Y variable (dependent variable) which is predicted or explained by linear regression and the X variabe (independent variable) or the predictor variable. It specifies how much variation in Y variable can be explained or predicted by the variation in X variable in a regression setting.

22. The coefficient of determination explains the relationship between two variables the proportion of variance in one variable accounted for by another variable and vice versa the cause–effect relationship between two variables all of the above 23. The ____________ assumption is met if, in a scatterplot, the distance from the points to the line is relatively equal all along the line. a. homoscedasticity b. linearity c. curvilinearity d. heterolinearity 24.

Use the value of the linear correlation coefficient r to find the coefficient of determination and the percentage of the total variation that can be explained by the linear relationship between the two variables. r 0.301 What is the value of the coefficient of determination? -(Round to four decimal places as needed.)
When two variables are measured and a determination regarding whether there is a numerical relationship between the variables, this is a(n): a. Experimental study b. Correlational Study c. Both
The value of the coefficient of determination ranges from -1 to +1 where a zero indicates no relationship between the variables True or false
You are testing the null hypothesis that there is no relationship between two variables, X and Y. From your sample of n = 22, you determine that SSR = 80 and SSE = 20. Construct the ANOVA table, test for model significance at a 0.05 level of significance and state your conclusion, and calculate the coefficient of determination and interpret its meaning.
A large sample of data is collected in order to study the relationship between the two variables X and Y to investigate whether X can be used to predict the value of Y. It is found that r = -.75. Which one of the following statements is true? A The coefficient of determination is equal to -.75 B The coefficient of determination is equal to .75 C The coefficient of determination is equal to -.5625 D The coefficient of determination...
