A mathematics teacher determines that the median score for the most recent test was 80 percent. Which of the following is the most accurate interpretation of the result? A The highest score on the test was 80 percent. B The average score on the test is 80 percent. C Half the students scored an 80 percent or below. \/ Median is the middle number in a data set. It is calculated by arranging the numbers from least to greatest and finding the number in the middle; if there is not one middle number, then the median is the average of the two numbers. For example, in the data set 1, 2, 3, 4 the median is 2.5 because 2.5 is the average of 2 and 3. If the median score is 80, then it can be assumed half the students scored below 80 and half the students scored above 80. D The most common score on the test is 80 percent.
