A)When the sample mean is a whole number
B)When the sample mean is not a whole number
C)When the sample variance is a whole number
D)When the sample variance is not a whole number

The computational formula is preferred over the definitional formula when computing SS for a sample when the sample mean is not a whole number. This is because the computat ional formula uses decimal estimates of the variance, which can lead to more accurate results than the definitional formula, which uses integer values.
