This is a simplified version of our descriptive statistics tool which calculates just the sample mean. It is intended for students and others who are looking for just this statistic. The sample mean is a common statistic which is calculated as the sum of the observations divided by the number of observations in the sample. This is also commonly referred to as the average of a …

21.04.2021 · The Probability of a Sample Mean. We saw in the previous section that if we take samples, the distribution of the sample means will be approximately normal. This will hold true even when the underlying population is not normally distributed, provided we take samples of n=30 or greater.

The normal distribution is often used to describe and approximate any variable that tends to cluster around the mean, for example, the heights of male students in a college, the leaf sizes on a tree, the scores of a test, etc. Use the "Normal Distribution" calculator above to determine the probability of an event with a normal distribution lying between two given values (i.e. P in the …

Learn how to find probabilities in statistics for a sample mean when its distribution is normal, not normal, or unknown.

One of the benefits of knowing the sampling distribution of the sample mean is that we can calculate the probability that $\bar{x}$ will be within a certain range of the population mean. Since the sample mean follows a normal distribution, calculating probabilities for $\bar{x}$ simply involves converting to the standard normal distribution.
