Frequency Of Exclusion

Frequency Of Exclusion
Frequency of exclusion refers to the rate of occurrences where a group is excluded from a sample or study. The frequency of exclusion would attempt to define the percentage or rate that a specified group is under-represented in a sample or study. Statistical study results lose their meaningfulness if the sample group does not accurately represent the entire population of interest.

For example, one could determine the rate at which persons with a certain blood type are excluded from a particular medical study. If a certain blood group is not properly represented in the research study, then the effects of a tested drug will not reflect the actual results that will occur when the drug hits the market.
