Mean and Mean Absolute Deviation

Front

What does MAD stand for in statistics?

Back

Mean Absolute Deviation.

Front

How do you calculate the Mean Absolute Deviation (MAD)?

Back

1. Find the mean of the data set. 2. Calculate the absolute distance of each data point from the mean. 3. Find the average of those absolute distances.

Front

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

Back

Find the average or mean of the data set.

Front

What is the significance of the absolute value in the calculation of MAD?

Back

The absolute value ensures that all distances are non-negative, allowing for a true average of deviations.

Front

If the mean of a data set is 50, what does it mean if a data point is 60 in terms of MAD?

Back

The distance from the mean is 10 (60 - 50 = 10).

Front

Calculate the mean of the following data set: 58, 38, 54, 48, 26, 36.

Back

The mean is 43.33.

Front

What is the Mean Absolute Deviation of the data set: 10, 9, 3, 8, 10?

Back

The Mean Absolute Deviation is 2.

Front

True or False: The absolute value of a number can be negative.

Back

False. The absolute value of a number is always positive.

Front

What is the Mean Absolute Deviation of the data set: 85, 90, 68, 75, 79?

Back

The Mean Absolute Deviation is 6.48.

Front

Why is it important to understand Mean Absolute Deviation in statistics?

Back

MAD provides insight into the variability or dispersion of a data set.
