Professor Clark gave her class a statistics exam. After the test, she told her class that the average score was 79%. What measure of central tendency is Professor Clark using?
Explanation
Answer: B - The mean, also commonly referred to as “the average,” is the sum of values in a set divided by the total number of items in a set. To arrive at the mean, Professor Clark added all of the scores, and then divided the total by the number of tests taken. The range is the set of values between the low and high scores in this set. The mode is the most frequent score in a set, and the median is the middle number in a set.
