In statistics, “x bar” (pronounced as “x bar”) represents the sample mean or the average of a set of numerical values.
To calculate x bar, you need to add up all the values in the sample and then divide the sum by the total number of values.
Let’s say you have a sample of numbers: 5, 7, 9, 3, and 2.
To find x bar, you add up all the numbers:
5 + 7 + 9 + 3 + 2 = 26
Next, count the total number of values in the sample, which in this case is 5.
Finally, divide the sum by the total number of values:
26 ÷ 5 = 5.2
So, the sample mean or x bar for this set of numbers is 5.2.
