Yet most researchers are less familiar with effect sizes than with significance tests, even in choosing among them. This article clarifies the concepts, formulae, and appropriate usage of the "variance explained" effect size indices, eta-squared, omega-squared, and epsilon-squared (η2,ω2,ε2...

The body mass index formula is easy to determine. It’s a simple calculation that takes into account your weight and height. The imperial BMI formula = Weight (LBS) x 703 ÷ Height (Inches²) The metric BMI formula = Weight (KG) ÷ Height (Metres²) If you wish to calculate your...

Using the formula above, the required sample size per group is 90, and thus the total sample size required is 180. This calculation can also be completed using the nQuery software, by selecting the “Two Sample Z-test” table, and entering the parameters above. The calculation again shows ...
The Keynesian Theory states that an increase in production leads to an increase in the level of income and therefore, an increase in spending. The value of MPC allows us to calculate the size of the multiplier using the formula: 1 / (1 – MPC) = 1 / (1 – 0.5) =2 ...
