The normal distribution shape of standard deviations from the mean is sometimes referred to as (A) error distribution (B) value table (C) property range (D) bell curve Correct Ans: (D) Explanation: Mass media researchers frequently describe the normal distribution as the bell curve. This is because its shape closely resembles a bell. In any data […]
