To find the mean absolute deviation (MAD) of a sample of teachers, follow these steps:

1. Calculate the average (mean) of the sample.
2. Find the absolute difference between each teacher's value and the mean.
3. Calculate the mean of these absolute differences.

The formula for MAD is:

MAD = Sum of (|teacher's value - mean|) / Number of teachers

Once you have the absolute differences for each teacher, sum them up, then divide by the total number of teachers to find the MAD. If you provide the data points (values of teachers), I can help you calculate the MAD.
