Mean Absolute Deviation

Front

What is the Mean Absolute Deviation (MAD)?

Back

The average distance between each data value and the mean.

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 second step to solving for the Mean Absolute Deviation?

Back

Subtract the mean from each original data point.

Front

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

Back

Find the mean of the NEW set of numbers.

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. 3. Take the absolute value of each result. 4. Find the mean of these absolute values.

Front

If the data set is 12, 25, 7, 14, 11, 30, what is the Mean Absolute Deviation?

Back

7.3

Front

What does 'absolute value' mean in the context of Mean Absolute Deviation?

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 formula for Mean Absolute Deviation?

Back

MAD = (Σ |x_i - mean|) / N, where x_i are the data points and N is the number of data points.

Front

What does a low Mean Absolute Deviation indicate?

Back

The data points are close to the mean, indicating low variability.
