Simple random sampling
Simple random sampling, also, known as ‘unrestricted random
sampling’; is applicable for small, homogenous, readily available
population and is used in clinical trials.
In simple random sampling each individual is chosen randomly and
entirely by chance.
So, each individual has the same probability of being chosen at any
stage during the sampling process.
For example : ?
Let us assume you had a school with 1000 students, divided equally
into boys and girls, and you wanted to select 100 of them for further
study.
You might put all their names in a bucket and then pull 100 names
