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.

Positive or Negative........I think...
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
it is da same as coefficient of determination
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.

True
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.
One other name is "coefficient of variation".
