Definition

The sample mean is the average of a sample, calculated by summing the sample values and dividing by the sample size.

Description

The sample mean is a measure of central tendency that provides an estimate of the population mean based on a sample. It is widely used in statistics for making inferences about populations from samples, playing a crucial role in hypothesis testing and confidence interval estimation. The sample mean is used in fields such as economics, biology, and psychology to analyze data and draw conclusions about larger populations.

In educational settings, the sample mean is introduced in lessons on data analysis and statistical inference. Students learn to calculate the sample mean and understand its significance in estimating population parameters. Teachers use the sample mean to explain concepts of sampling and variability, emphasizing its role in statistical reasoning and decision-making.
