Select the true statement(s) about the measures of variability. The sample standard deviation is always greater than or equal to 0. Every deviation about the mean is non-negative. The sample standard deviation and the population standard deviation are always the same value. Quartiles divide the data into four parts. The first quartile is always less than or equal to the third quartile. The computational formula for the sample variance is used only for large data sets.
