Calculation of Mean Deviation in Excel

Formula Creation

To calculate the Mean Deviation for the set of numbers 5, 15, 10, 5, 10 in Excel, the following concise steps can be utilized.

Steps to Create the Formula:

Calculate the Mean (Average) of the data set.
Determine the Absolute Deviation from the Mean for each number.
Calculate the Mean of these Absolute Deviations.

Excel Formula

Assuming the numbers 5, 15, 10, 5, and 10 are stored in cells A1 through A5, the Mean Deviation can be computed with the following formula:

=AVERAGE(ABS(A1:A5-AVERAGE(A1:A5)))

Explanation of the Formula

AVERAGE(A1:A5): This part calculates the mean (average) of the values in the range A1 to A5.
ABS(A1:A5 - AVERAGE(A1:A5)): This segment computes the absolute deviations from the mean for each data point. The ABS function returns the absolute value.
AVERAGE(...): Finally, it calculates the average of these absolute deviations, resulting in the Mean Deviation.

Practical Example

Suppose you have the following values in Excel:

A
5
15
10
5
10

Place the values in cells A1 to A5.
Enter the Mean Deviation formula in another cell (let's say B1):

=AVERAGE(ABS(A1:A5-AVERAGE(A1:A5)))

When you execute the formula, it will return the Mean Deviation for the provided dataset.

Conclusion

The given steps and the formula allow for an efficient calculation of the Mean Deviation in Excel for any set of numbers. Understanding how to implement this formula enhances data analysis skills and supports precision in statistical calculations.
