How do you calculate coefficient of variation in spss?
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.
Is it true that the standard deviation can equal zero in a data set?
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.
What is the coefficient of variation?
The coefficient of variation is the ratio between the standard deviation and the mean.
What does it mean if the mean is doubled but the standard deviation is the same?
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.
How can you describe variation in a set of data?
measures of variation
Is it possible for a coefficient of variation of a set of data to be zero Explain.?
Yes it is. If all the observations have the same non-zero value then the coefficient of variation will be zero.
Is it possible for a coefficient of variation to be negative?
Of course it is! If the mean of a set of data is negative, then the coefficient of variation will be negative.

Is the the coefficient of variation for a data set is the mean divided by the standard deviation expressed as a percentage?
no

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.
Does the coefficient of variation measure variability in a data set relative to the size of the arithmetic mean?
Yes.
How do you calculate coefficient of variation?
The coefficient of variation is calculated by dividing the standard deviation of a dataset by the mean of the same dataset, and then multiplying the result by 100 to express it as a percentage. It is a measure of relative variability and is used to compare the dispersion of data sets with different units or scales.

If the coefficient of determination for the data set is 0.75 and the SSE for the data set is 13 what is the SST for the data set?
It is 52.
