Detailed explanation-1: -A population is the collection of ALL outcomes, responses, measurements, or counts that are of interest. A sample is a subset of a population. A parameter is a numerical description of a population characteristic. A statistic is a numerical description of a sample characteristic.
Detailed explanation-2: -The population is the set of all measurements of interest to the investigator. Typically, there are too many experimental units in a population to consider every one. However, if we can examine every single one, we conduct what is called a census.
