In a skewed distribution, what is the minimum amount of observations that will fall between +/- 1.5 standard deviations from the mean? A. 44%. B. 56%. C. 95%.
Because the distribution is skewed, we must use Chebyshev’s Inequality, which states that the proportion of observations within k standard deviations of the mean is at least 1 – (1 / k2).
