This Question: 1 pt 47 of 50 (38 complete) ? The ccefficent of determination 2 is the ratio of which two types of varetons? What does 2 measure? Whet does 1 - 2 measure? The ccoffciont of detormination is the ratio of the explained variation to the total variation O A The coefficent of determinaton is the ratio of the total variaton to the unexplained varlaton. O C. The coemicent of dotermination is the ratio of the total variation to the explained variation. Choose the correct answer below ? B. Te coefficient of determinaton is the ratio of the explained vanaton to the total variation O D. The coefficient of determination is the ratio of the unexplained varaton to the total variation. OA. The coefficient of determineton is the percent of the predicled values that equal the actual dala values. ? c. The coefficent of determination is a measure of how closely two variables vary together Choose the correct answer below O B. O D- The coefficient of determination is the percent of the variation that is unexplained. The coefficient of determination is the percent of variation of y thet is explained by the relationship between x and y OA The vai the percent of the prodicted vale that eqal the actual data values. O B. The vaue 1 r2 s a measure of how closely two variables vary together O C. The value 1 is the percent of variafon of y that is explsined by tho relationship betwoon x and y. O D. The vaue 12s the percent of the varlation that is unexplaned
