Coefficient of Mean Deviation Calculator





Formula

The formula to calculate the Coefficient of Mean Deviation (CMD) is:

\[ CMD = \frac{MD}{AM} \]

Where:

What is the Coefficient of Mean Deviation?

The coefficient of mean deviation is a measure of relative dispersion that indicates the extent of variability in a data set relative to its mean. It is calculated by dividing the mean deviation by the arithmetic mean. This coefficient provides a dimensionless number that allows for comparison between different data sets, regardless of their units of measurement. It is particularly useful in statistical analysis for understanding the consistency and reliability of data.

Example Calculation

Let's assume the following values:

Step 1: Calculate the Coefficient of Mean Deviation (CMD):

\[ CMD = \frac{5}{20} = 0.25 \]

Therefore, the Coefficient of Mean Deviation (CMD) is 0.25.
