Professor Bullock gave his class a statistics exam. After the test, he told his class that most of the students earned 100%. What measure of central tendency is Professor Bullock using?
  1. Range
  2. Mean
  3. Median
  4. Mode
Explanation
Answer: D - The mode is the most frequent score in a set. This means that some students may have earned very low scores on the test, but 100% was the most frequent score. The range is the set of values between the low and high scores in a set. All other scores fall within this range. The mean is the sum of values in a set divided by the total number of items in a set, and the median is the middle number in a set.
