2. Identify the mode in the frequency distribution. Mode(9) = 3. What is the range of this frequency distribution? Range = On average, how much does each score in this distribution vary from the mean score? The steps for calculating the average deviation (AD) of a frequency distribution is as follows: i. Determine the deviation scores for each score in the frequency distribution (in other words, how much does each individual score vary from the mean score?). 11. Find the sum of the deviation scores. Divide the sum of the deviation scores by the total number of scores to obtain the average deviation. Complete the table below (10 points)
