What is the purpose of inferential statistics?

The purpose of inferential statistics is to make predictions or inferences about a population based on a sample of data. This branch of statistics enables researchers to generalize findings from a smaller group to a larger one while accounting for uncertainty. For example, if researchers conduct a survey on a sample of one hundred individuals to understand voting preferences, inferential statistics allows them to estimate the preferences of the entire population of eligible voters. This process often involves hypothesis testing and confidence intervals, providing researchers with tools to assess the reliability and validity of their conclusions.
