Front

What is the first step to solving for the Mean Absolute Deviation?

Back

Find the mean of the given data set.

Front

What is the definition of the Mean Absolute Deviation?

Back

The average distance between each data value and the mean.

Front

Find the Mean Absolute Deviation of the set: 10, 5, 7, 14, 19, 32, 25.

Back

8

Front

Find the Mean Absolute Deviation of the set: 56, 21, 55, 30, 34.

Back

13.04

Front

Find the Mean Absolute Deviation of the set: 12, 25, 7, 14, 11, 30.

Back

7.3

Front

What is the formula for calculating Mean Absolute Deviation?

Back

MAD = (Σ|x - mean|) / N, where x is each data point, mean is the average, and N is the number of data points.

Front

What does 'absolute' refer to in Mean Absolute Deviation?

Back

It refers to the non-negative distance from the mean, ignoring direction.

Front

Why is Mean Absolute Deviation important in statistics?

Back

It provides a measure of variability or dispersion in a data set.

Front

How does Mean Absolute Deviation differ from standard deviation?

Back

MAD uses absolute values, while standard deviation squares the differences.

Front

What is the Mean Absolute Deviation of a data set with all identical values?

Back

0, because there is no deviation from the mean.
