What is Sample Size?

Sample size definition A sample size is a part of the population chosen for a survey or experiment. The sample size is an important feature of any empirical study in which the goal is to make inferences about a market segment from a sample.

It would be expensive and time-consuming to collect data from the whole population of a market. Therefore, market researchers make extensive use of sampling from which, through careful design and analysis, marketers can draw information about their chosen market.
