The mean average deviation is the same as the mean deviation (or the average deviation) and they are, by definition, 0.
You calculate the mean.For each observation, you calculate its deviation from the mean.Convert the deviation to absolute deviation.Calculate the mean of these absolute deviations.
we calculate standard deviation to find the avg of the difference of all values from mean.,
There is no single function in Excel.You calculate the mean (average).For each observation, you calculate its deviation from the mean.Convert the deviation to absolute deviation.Calculate the mean (average) of these absolute deviations.
In the same way that you calculate mean and median that are greater than the standard deviation!
You don't need to. Average deviation (about the mean) is always zero!
You cannot "solve" a mean squared deviation". You can calculate it or use it, but there is nothing to solve!
It is easy to understand and to calculate
Standard deviation is how much a group deviates from the whole. In order to calculate standard deviation, you must know the mean.
in order to calculate the mean of the sample's mean and also to calculate the standard deviation of the sample's
The mean and standard deviation do not, by themselves, provide enough information to calculate probability. You also need to know the distribution of the variable in question.
