This sample size is based Jacob Cohen’s requirement for statistical power analysis of a one-way ANOVA test (Cohen‚ 1992). In order to reduce the possibility of errors‚ a medium effect size is selected with an a level of .01 at a power of .80. With a small a value‚ there is a decreased risk of a Type I error where

According to Merriam-Webster statistics is “a branch of mathematics dealing with collection‚ analysis‚ interpretation and presentation of masses of numerical data.” There are different types of statistical data – numerical‚ categorical‚ and ordinal. Numerical data can be broken out into two groups: Discrete Data and Continuous Data. Numerical data covers measurement. Discrete data represents items that can be counted versus continuous data represents
