A (population) effect size θ based on means usually considers the standardized mean difference (SMD) between two populations: 78 where μ1 is the mean for one population, μ2 is the mean for the other population, and σ is a standard deviation based on either or both populations. In the practical setting the population va...

In the treatment group, six students pass for every one who fails, so the odds of passing are six to one (or 6/1 = 6). The effect size can be computed by noting that the odds of passing in the treatment group are three times higher than in the control group (because 6 divided by 2 is 3). Therefore, the odds ratio is 3....

It is important to understand the terms "heterozygous", "homozygous", "double heterozygote" (or homozygote), "dominant allele" and "recessive allele" when using the Punnett square method. For multiple traits, using the "forked-line method" is typically much easier than the Punnett square. Phenotypes may be predicted wi...
