How do you work out stratified sampling?

In: Math and Arithmetic, Information Science and Libraries, Engineering [Edit categories]

Answer:

If a sample of size s is to be taken from a population of size n, then every ⁿ/_s member of the population is tested. The starting point is chosen at random.
If we want to test a 100-strong sample from a population of 2000, we test every ²⁰⁰⁰/₁₀₀ = every 20^th member. We use random numbers to determine the starting point.
