Difference of Means Calculator





Formula

To calculate the Difference of Means (DM):

\[ \text{DM} = \text{M1} - \text{M2} \]

What is the Difference of Means?

The Difference of Means, also known as a mean difference or average difference, is a statistical method used to compare the averages of two different groups to determine if they are significantly different from each other. It is calculated by subtracting the mean (average) of one group from the mean of the other group. This method is commonly used in experiments and observational studies to test hypotheses and draw conclusions about the populations from which the groups are sampled.

Example Calculation 1

Let's assume the following values:

Step 1: Use the formula:

\[ \text{DM} = 75 - 65 = 10 \]

The Difference of Means is 10.

Example Calculation 2

Let's assume the following values:

Step 1: Use the formula:

\[ \text{DM} = 90 - 85 = 5 \]

The Difference of Means is 5.
