MAD Mean Absolute Deviation

Front

What is Mean Absolute Deviation (MAD)?

Back

Mean Absolute Deviation (MAD) is a measure of the dispersion of a set of data points. It represents the average distance between each data point and the mean of the data set.

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 of each result. 3. Find the average of these absolute values.

Front

What is the first step in finding the MAD of a data set?

Back

The first step is to calculate the mean (average) of the data set.

Front

If the data set is 5, 11, 2, 7, 16, what is the mean?

Back

The mean is 8.2.

Front

Given the data set 100, 104, 107, 105, what is the MAD?

Back

The Mean Absolute Deviation is 2.

Front

What does a lower MAD indicate about a data set?

Back

A lower MAD indicates that the data points are closer to the mean, showing less variability.

Front

What does a higher MAD indicate about a data set?

Back

A higher MAD indicates that the data points are more spread out from the mean, showing greater variability.

Front

Calculate the MAD for the data set: 58, 38, 54, 48, 26, 36.

Back

The Mean Absolute Deviation is 10.

Front

What is the MAD for the ages: 11, 34, 16, 18, 22, 30, 18, 20, 15, 16?

Back

The Mean Absolute Deviation is 5.2.

Front

For the data set 1, 4, 8, 9, 10, 11, 15, what is the MAD?

Back

The Mean Absolute Deviation is 3.4.
