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

Yes, you can have a negative coefficient in a direct variation. So if you had y = -7x, that would be a direct variation. If you have y = -x, I do not know, if that is what you mean. Hope it helped.
0% to 100%
Yes it is. If all the observations have the same non-zero value then the coefficient of variation will be zero.
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.
it is da same as coefficient of determination
The coefficient of variation should be computed only for data measured on a ratio scale, as the coefficient of variation may not have any meaning for data on an interval scale. Using relative values instead of absolute values can cause the formula to give an incorrect answer.
The second set of numbers are less variable; the coefficient of variation is halved. The second set of numbers are less variable; the coefficient of variation is halved.

coefficient of variation
Yes, a coefficient of a variable can be negative.
True
The CV is a way to summarize the variation of results from the mean.
