How do you find the mean of a set of numbers?
Recall that to find the mean, you add up all the numbers in a set and then divide the sum by the total number of values.

The mean, or arithmetic mean, is the average value of a set of numbers. More specifically, it's the measure of a "central" or typical tendency in a given set of data.
What is the meaning of "average"?
Mean —often simply called the "average"— is a term used in statistics and data analysis. In addition, it's not unusual to hear the words "mean" or "average" used with the terms "mode," "median," and "range," which are other methods of calculating the patterns and common values in data sets.

What is mean in statistics?
In statistics, the mean summarizes an entire dataset with a single number representing the data’s center point or typical value. It is also known as the arithmetic average, and it is one of several measures of central tendency. It is likely the measure of central tendency with which you’re most familiar! Learn how to calculate the mean, and when it is and is not a good statistic to use!
Why is the mean misleading?
In these cases, the mean can be misleading because because it might not be near the most common values. Consequently, it’s best to use the average to measure the central tendency when you have a symmetric distribution.
What is sample average in statistics?
In statistics, analysts often use a sample average to estimate a population mean. For small samples, the sample mean can differ greatly from the population. However, as the sample size grows, the law of large numbers states that the sample average is likely to be close to the population value.
Which is better, median or standard deviation?
For skewed distributions, it’s often better to use the median, which uses a different method to find the central location. Note that the mean provides no information about the variability present in a distribution. To evaluate that characteristic, assess the standard deviation.
Does the mean always find the center of the data?
However, the mean does not always find the center of the data. It is sensitive to skewed data and extreme values. For example, when the data are skewed, it can miss the mark. In the histogram below, the average is outside the area with the most common values.
