Remember r-squared is the percentage of explained variability in Y (weight) that can be explained by the relationship with (X). Sentence to explain r-square for men’s age and weight: The r-squared value for the men’s age and weight was 0.0815 or 8.2%. Explain this statistic to someone.
R-squared (R2) - Formula | Example | Calculation | Use Explanation
Recall that the R-squared value is the square of the correlation coefficient. (Most statistical texts show the correlation coefficient as "r", but Excel shows the coefficient as "R". Whether you write is as r or R, the correlation coefficient gives us a measure of the reliability of the linear relationship between the x …

The company may also support the choice of a low value of E by achieving a high R-squared – e.g., 0.80 or higher – when using a regression analysis technique;
