What is Mean Absolute Deviation (MAD)?

Back

The average distance of a data's values from the mean.

Front

How do you calculate the Mean Absolute Deviation?

Back

1. Find the mean of the data set. 2. Subtract the mean from each data point and take the absolute value. 3. Find the average of those absolute values.

What does the term 'absolute value' mean?

Back

The distance of a number from zero on the number line, regardless of direction.

Front

Why is Mean Absolute Deviation important?

Back

It provides a measure of variability in a data set, indicating how spread out the values are.

Front

What is the relationship between Mean and Mean Absolute Deviation?

Back

MAD is calculated based on the mean; it measures how much individual data points deviate from the mean.

Front

If all data points are the same, what is the MAD?

Back

0, because there is no deviation from the mean.
