Can the variance of a data set ever be negative? Explain. Can the variance ever be smaller than the standard deviation? Explain. Choose the correct answer below. A. The variance of a data set cannot be negative because it is the sum of the squared deviations divided by a positive value. Variance can be smaller than the standard deviation if the variance is less than 1. B. The variance of a data set cannot be negative because deviation from the mean is always a positive value. Variance cannot be smaller than the standard deviation because the variance is the square of the standard deviation. C. The variance of a data set can be negative if all of the data values are negative. Variance cannot be smaller than the standard deviation because the standard deviation is th
