measures of variation
Yes, if there is no variation: all the data have to have the same value and that value must be non-zero.
The coefficient of variation is a method of measuring how spread out the values in a data set are relative to the mean. It is calculated as follows: Coefficient of variation = σ / μ Where: σ = standard deviation of the data set μ = average of the data set If you want to know more about it, you can visit SilverLake Consulting which will help you calculate the coefficient of variation in spss.
The standard deviation is a measure of how much variation there is in a data set. It can be zero only if all the values are exactly the same - no variation.

Of course it is! If the mean of a set of data is negative, then the coefficient of variation will be negative.

Standard Deviation
The coefficient of variation is usually calculated by diving the standard deviation by the mean of a particular set of data. The coefficient of variation is usually expressed as CV.
no
There are a number of appropriate displays to show the measures of variation for a data set. Different graphs can be used for this purpose which may include histograms, stemplots, dotplots and boxplots among others.
Yes.
