Random Sampling – A method of sampling whereby all the participants have an equal chance of being selected in a population take part in the study. An example might be random generation of names by a computer or `drawing names out of a hat`.

· Random sampling is `fair`. Everyone has an equal chance of being selected and the sample is likely to be representative.
