What are Population and Sample?

The entire group about whom you want to make conclusions is a population.
A sample is a subset of the population you will collect data from.
The sample size is always smaller than the population’s total size.
The population moments most often used are: 

  1. mean
  2. variance
  3. skewness
  4. kurtosis

Why are population and sample important?

For researchers to generalise results from observations of the sample to the target population, they need a sample that is typical of the target population. Both the sampling frame and the sample should, in theory, be representative of the population in every way.
