What does mean absolute deviation indicates?
The mean absolute deviation for a set of data is a measure of the spread of data. It is calculated as follows:Find the mean (average) value for the set of data. Call it M.For each observation, O, calculate the deviation, which is O - M.The absolute deviation is the absolute value of the deviation. If O - M is positive (or 0), the absolute value is the same. If not, it is M - O. The absolute value of O - M is written as |O - M|.Calculate the average of all the absolute deviations.One reason for using the absolute value is that the sum of the deviations will always be 0 and so will provide no useful information. The mean absolute deviation will be small for compact data sets and large for more spread out data.
What is the mean absolute deviation of the following data 6 8 9 2 1 22?
The mean absolute deviation is 5
I am given 9 15 28 10 and 8 what is the mean absolute deviation for this data?
The mean deviation or absolute mean deviation is the sum of the differences between data values and the mean, divided by the count. In this case the MAD is 6.
Define mean absolute deviation?
The average mean absolute deviation of a data set is the average of the absolute deviations from a central point. It is a summary statistic of statistical dispersion or variability.
What does absolute deviation mean?
The Mean Absolute Deviation indicates how clustered (close together) the data is, i also indicates the average of the distance of the values and the mean.
Difference between standard deviation and mean devition?
The mean deviation (also called the mean absolute deviation) is the mean of the absolute deviations of a set of data about the data's mean. The standard deviation sigma of a probability distribution is defined as the square root of the variance sigma^2,
What is the mean absolute deviation of the set of data 16 20 24 25 28 29 31 35?
The mean absolute deviation (from the mean) is 4.75
What is the mean absoulute deviation of the data set 1247262538453535413932251830?
The mean absolute deviation for one number is always zero.
What does the mean absolute deviation tell you about how spread out the data are?

What does the mean absolute deviation tell you about a set of data?
It is a measure of the spread or dispersion of the data.
What is the arithmetic mean of the absolute values of the deviations of the individual values from the mean in a data set?
It is the mean absolute deviation.
