A dimensionless measure of the degree of presence of a phenomenon in the population of interest.
Note: In the case of continuous variables, it is generally defined as the difference in means between the experimental and control groups, divided by the standard deviation of the control group or both groups. When different scales (pain assessment, for example) are used to measure an outcome, they become comparable.
Note: This measure is used to determine the size of a sample.
