In mathematics, what people usually call the "average" is properly known as the "mean" or the "mean number." There are actually two other types of averages – the "mode" and "median" – that you'll learn about when you study statistics in high school and beyond. But for most mathema...
A sample of data is often summarized using two statistics: its average value and a measure of how spread out it is. Variance and standard deviation are both measures of how spread out it is. Several functions let you calculate variance in Excel. Below, we'll explain how to decide which o...

How to find a coefficient of variation in Excel. You can calculate the coefficient of variation in Excel using the formulas for standard deviation and mean. For a given column of data (i.e. A1:A10), you could enter: “=stdev(A1:A10)/average(A1:A10)) then multiply by 100. ...
Step 1:In cell E2, use the formula as an AVERAGE to calculate the sample mean. Use formula as=AVERAGE(B2:B11). Step 2:To calculate Sample Standard Deviation, use the STDEV.P function in cell E3. Use the formula as=STDEV.P(B2:B11)to capture the standard deviation for data. ...
Find the upper limit by adding the value returned by the Confidence function to your mean, which is the output of the Average function. Find the lower limit by subtracting the output of the Confidence function from the mean. The range between these two limits is the confidence interval. ...
The Standardize function is another built-in function in Excel that can be used for Z Score calculation. The function syntax is: =STANDARDIZE(X, Mean, Standard Deviation) The function takes three arguments: X is the data point, Mean is the average value, and Standard Deviation is the measure...
