To find the median, we first need to arrange the scores in order from least to greatest:
2, 5, 6, 7, 9, 9, 10, 10
Since there are 8 numbers, the median will be the average of the 4th and 5th numbers when arranged in order. In this case, the 4th number is 7 and the 5th number is 9.
Therefore, the median is (7 + 9) / 2 = 8.
Use the table and image to answer the question.
Students
Class Section A B C D E F G H
1 2 7 9 9 10 10 7 6
2 10 10 9 8 10 6 9 5
3 6 8 9 9 7 10 10 7
A line with arrows at both ends is labeled 1 to 10 in increments of 1. The title, Quiz Scores, is below the numbers. The dots are stacked above the line in alignment with the numbers on the line. There is 1 dot above 2; 1 dot above 5; 3 dots about 6; 4 dots above 7; 2 dots above 8; 6 dots above 9; and 7 dots above 10.
Mr. Wang gave a test to his students. The spreadsheet shows the quiz scores out of a possibility of 10. What is the median if the 8 is replaced with a 10?
