University of Hawai'i at Manoa QUESTION: In a recent paper on cloze tests (Brown, Yamashiro, & Ogane, 2001, p. 143), you mentioned that the coefficients of determination for cloze tests vary from .19 to .83. Can you explain what coefficients of determination are? How are they ...

How do you interpret a coefficient of determination of r2 = 0.82? Identify and describe two factors that affect reliability coefficients. Be sure to define a reliability coefficient in your answer. If the coefficient of determination is equal to one, what can be said about the coefficient of co...
The coefficient of determination of a set of data points is 0.766 and the slope of the regression line is negative 4.28. What is the linear correlation coefficient? What is the difference between regression coefficients and correlation coe...

High values of R2 are particularly useful when using the model for predictions! (More on this later!) Observe that seemingly high values of r, e.g. r=0.70, explain only about 50% of the variability in the response variable y. So take care when interpreting correlation coefficients. a low...
of the extremes. In fact, the fraction of the total spatial variation ofTXxandTNnchanges which is explained by the changes in the seasonal averages hardly exceeds 50%, as indicated by the coefficients of determination\({R}_{{{\rm{red}}}^{2}\)in Table1. These are obtained by Eqs. (...
Effect size (f2) tells the importance of exogenous variables on the coefficient of determination of endogenous variables. According to Cohen (1988), the value of effect size (f2) should lie between 0.02 to 1. A value range of 0.02–0.15 represents a weak effect, 0.15–0.35 represents a mode...
