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.
Of course it is! If the mean of a set of data is negative, then the coefficient of variation will be negative.
it is da same as coefficient of determination
coefficient of variation
I have found the coefficient of variation of the first natural numbers and also other functions.
Yes it is. If all the observations have the same non-zero value then the coefficient of variation will be zero.
Of course it is! If the mean of a set of data is negative, then the coefficient of variation will be negative.

The diffusion coefficient depends on temperature in direct negative exponent.
Positive or Negative........I think...
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
y=3x is a direct variation in that y varies directly with x by a factor of 3. Any linear equation (a polynomial of degree 1, which is a polynomial equation with a highest exponent of 1), is a direct variation of y to x by some constant, and this constant is simply the coefficient of the "x" term. Other examples: y=(1/2)x is a direct variation, and the constant of variation is 1/2 y=-9x is a direct variation, and the constant of variation is -9
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. 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.
Yes, a coefficient of a variable can be negative.
coefficient of variation
True
The CV is a way to summarize the variation of results from the mean.
