Analysis is conducted to make inferences about a population using data obtained from the sample. Population : A population is the complete set of individuals, objects, or scores that the investigator is interested in studying. In actual experiment, the population is the larger group of individuals from which the subjects run in the experiment have been taken. Parameter : A parameter is a number calculated on population data. It quantifies a characteristic of the population. It should be noted that a statistic and a parameter are very similar concepts. Sample : A sample is a subset of the population. In an experiment, for economical reasons, the investigators usually collect data on a smaller group of subjects than the entire population.
