-The Variance of a Probability Distribution Can Be Described As

Question 47

Multiple Choice

  -The variance of a probability distribution can be described as: A) a measure of the riskiness of a probability distribution and is calculated by finding the square root of the probability-weighted squared deviations of the possible outcomes. B) a measure of the riskiness of a probability distribution and is calculated by finding the probability-weighted squared deviations of the possible outcomes times two. C) a measure of the amplitude of a probability distribution and is calculated by finding the square root of the probability-weighted squared deviations of the possible outcomes. D) a measure of the riskiness of a probability distribution and is calculated by finding the probability-weighted squared deviations of the possible outcomes.
