WebDec 29, 2023 · The symbol for a sample mean is x̅, which you pronounce as X-bar. This type of average can be less useful because it finds only the typical height of a particular sample. However, if we collect a random sample, we can use x̅ to estimate µ. The process allows us to use the sample to estimate the properties of a population.
