The coefficient of determination for estimating packaging costs for a local shipper was determined to be 0.84. Which of the following statement is not correct? Coefficient of determination values close to zero suggest that the equation is very useful. The coefficient of determination is a measure of the percent of variation in the dependent variable explained by variations in the independent variable. Coefficient of determination is often referred to as R-squared by statisticians. The coefficient of determination can have values...

Which of the following statements is false about the coefficient of determination r2
Which of the following statements are not correct? The
coefficient of determination, denoted by r^2 is interpreted as the
proportion of observed y variation that cannot be explained by the
simple linear regression model. The higher the value of the
coefficient of determination, the more successful is the simple
linear regression model in explaining y variation. If the
coefficient of determination is small, an analyst will usually want
to search for an alternative model (either a nonlinear model or a...
