If a cognitive psychologist nds that a group of one-yearold children can name 3, 3, 3, 4, 4, 5, 6, 7, 8, 9, 10, and 35 things, A. the most useful measure of central tendency will be the B. Why? I Q11. A distribution is negatively skewed. When reading the results from left to right, the measures of central tendency are most likely to be in this order A. mean = 30, median = 50, mode = 70 B. mean = 30, median = 70, mode = 50 C. mean = 50, median = 50, mode = 50 D. mean = 70, median = 50, mode = 30 Q12.
