What is mean deviation and why is quartile deviation better than mean deviation?

None.The mean of a single number is itself.Therefore deviation from the mean = 0Therefore absolute deviation = 0Therefore mean absolute deviation = 0None.The mean of a single number is itself.Therefore deviation from the mean = 0Therefore absolute deviation = 0Therefore mean absolute deviation = 0None.The mean of a single number is itself.Therefore deviation from the mean = 0Therefore absolute deviation = 0Therefore mean absolute deviation = 0None.The mean of a single number is itself.Therefore deviation from the mean = 0Therefore absolute deviation = 0Therefore mean absolute deviation = 0

No. The mean deviation is 0. Always.

The mean average deviation is the same as the mean deviation (or the average deviation) and they are, by definition, 0.

mean deviation =(4/5)quartile deviation

There is no statistical term such as "deviation mean".

Information is not sufficient to find mean deviation and standard deviation.

The mean deviation from the median is equal to the mean minus the median.

It means that the observed value is greater than that which might be expected under the model being used. Often, it is deviation from the [arithmetic] mean.

No. The average of the deviations, or mean deviation, will always be zero. The standard deviation is the average squared deviation which is usually non-zero.

You don't need to. The mean deviation is, by definition, zero.

The deviation about the mean of a single number is always zero.

Coefficient of deviation (CV) is a term used in statistics. It is defined as the ratio of the standard deviation (sigma) to the mean (mu). The formula for CV is CV=sigma/mu.

to find percent deviation you divide the average deviation into the mean then multiply by 100% . to get the average deviation you must subtract the mean from a measured value.

the sample mean is used to derive the significance level.

standard deviation

false

Mean and standard deviation are not related in any way.

The mean absolute deviation of this problem is 6.

Standard deviation is the variance from the mean of the data.

Standard deviation can be greater than the mean.

yes

Standard deviation is a measure of variation from the mean of a data set. 1 standard deviation from the mean (which is usually + and - from mean) contains 68% of the data.

The mean is the average

no the standard deviation is not equal to mean of absolute distance from the mean
