Does dichotomizing the dependent variable (i.e. logistic regression) decrease power in relation to a continuous dependent variable?
Calculate the vapor pressure of water, in torr, above a solution prepared by dissolving 65.40 g of ZnCl2 in 445.0 g of water at 323.0 K. The vapor pressure of pure water at 323.0 K is 92.50 torr.
This question has to do with power. Suppose in a clinical study you have two groups with 10 subjcects in each group. No significance at the .05 level is found but there is a medium effect size, which is judged to be of practical significance. What sh
