- is used to calculate the sample size (n) given the population size (N) and a margin of error (e).
- it's a random sampling technique formula to estimate sampling size
-It is computed as n = N / (1+Ne2).
whereas:
n = no. of samples
N = total population
e = error margin / margin of error
Step-by-step explanation:
If a sample is taken from a population, a formula must be used to take into account confidence levels and margins of error. When taking statistical samples, sometimes a lot is known about a population, sometimes a little and sometimes nothing at all. For example, we may know that a population is normally distributed (e.g., for heights, weights or IQs), we may know that there is a bimodal distribution (as often happens with class grades in mathematics classes) or we may have no idea about how a population is going to behave (such as polling college students to get their opinions about quality of student life). Slovin's formula is used when nothing about the behavior of a population is known at at all.
