Effect size for multiple linear regression
WebSep 11, 2015 · 6. Cohen's d is the mean difference divided by the (pooled) standard deviation of the data within the groups. Indeed, the coefficient for the dummy variable gives you the mean difference, but instead of dividing by the standard deviation of the dependent variable, you should divide by the (pooled) within-group standard deviation. WebOption (a) is incorrect because standardized coefficients are not used to determine the equation of the line in multiple linear regression. The equation of the line is determined …

WebAug 3, 2010 · For someone with a pulse rate 1 beat per minute faster of the same age, we’d predict that such a person would have a blood pressure 0.056 units higher. That “of the same age” is key! If the new person with the faster pulse has a different age, then our prediction wouldn’t just go up by 0.056; we’d also have to adjust for the new person’s age.
