A drug was given to Sports Science students of approximately the same weight. At the end of 20 days, their increase in weight and their average daily food intake were recorded. The data were as follows: Intake, x 26 10 27 16 19 23 18 24 (g per day) Gain, y 47 29 43 32 41 50 48 41 (g per day) The coefficient of determination has a value of 0.85 and measures the proportion of variation in the independent variable (x) explained by its linear relationship with the dependent variable (y) 0.52 and measures the...
