WebI’ve seen a lot of people get upset about small R² values, or any small effect size, for that matter. I recently heard a comment that no regression model with an R² smaller than .7 should even be interpreted. Now, there may be a context in which that rule makes sense, but as a general rule, no. Just because effect size is small doesn’t ... WebWe ask what would be the probability of a one-tailed Z-test correctly rejecting the null hypothesis when comparing a mean of sample size = 4 drawn from a population with a mean μ 1 of 9.59 μmol/litre.
