Absolute Mean Deviation-6th Grade

Front

What is the Mean Absolute Deviation (MAD)?

Back

The 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. Calculate the absolute deviations from the mean for each data point. 3. Find the mean of those absolute deviations.

Front

What is an absolute deviation?

Back

An absolute deviation is the distance between a data point and the mean, expressed as a positive value. It is calculated as |x - mean|.

Front

If the mean of a data set is 10, what is the absolute deviation of the value 7?

Back

The absolute deviation is |7 - 10| = 3.

Front

What is the first step in calculating the Mean Absolute Deviation?

Back

The first step is to find the mean of the data set.

Front

What does it mean if the Mean Absolute Deviation is low?

Back

A low Mean Absolute Deviation indicates that the data points are close to the mean, suggesting less variability in the data.

Front

What does it mean if the Mean Absolute Deviation is high?

Back

A high Mean Absolute Deviation indicates that the data points are spread out over a wider range, suggesting more variability in the data.

Front

What is the second step in calculating the Mean Absolute Deviation?

Back

The second step is to find the distance each value is from the mean.

Front

What is the third step in calculating the Mean Absolute Deviation?

Back

The third step is to find the mean of the absolute deviations.

Front

If the mean of a data set is 8, what is the deviation of 5?

Back

The deviation is 5 - 8 = -3.
