The list shows the ages of first-year teachers in one school system. What is the mode of the ages?
23, 42, 21, 25, 23, 24, 23, 24, 37, 23, 39, 51, 63, 24, 55
the answer is 24 because it is in the middle and mode is the most center number in the line. if there are 2 in the middle, you add them together then divide by 2 ie: (1+7)/2
