What is simple random sampling?

• This is a method that uses intact groups called clusters.

• This is done by using chance methods or random numbers.

• This is done by numbering each subject of the population and then selecting every kth number.

• This is a method of sampling that involves the division of a population into smaller sub-groups known as strata.
