Statistics questions. Both multiple choice. related to mean, median, and mode. Please help. Thank you

36. One of the key points of this activity is that the sum of the distances from the mean (i.e., the deviation scores) ALWAYS equals 0. The positive and negative deviations will ALWAYS balance out. This balancing of distances will ALWAYS occur even when the number of positive and negative deviations is unequal. Which of the following statements is always true about the mean? (Choose all that apply.) a The mean will always be the middle score; it will have the same number of scores above it and below it. b. The mean will always be the most common score in a distribution. c. The mean is the only value that exactly balances the distances of the deviations to the left and right of the mean. 37. The deviation scores for all distributions of scores always sum to zero. However, distributions of scores can vary quite a bit with regards to the typical distance scores are from the mean (deviation score). Which of the following distributions would have a greater typical deviation score? a. A class where everyone is between the ages of 20 and 21. b. A class where the ages range between 19 and 50
