Systematic Samples

Definition

Systematic samples are obtained by selecting every kth individual from the population. The first individual is randomly chosen between 1 and k.

Analogy

Think of systematic samples like picking every nth slice of pizza from a whole pizza. You start by randomly choosing which slice to begin with (between 1 and n), and then continue picking every nth slice after that.
