The median score is the middle number . BUT you have to rewrite the numbers from least to greatest THEN cross out first number then last number and keep repeating until you are left with one number in the middle . If you are left with two numbers in the middle then add them and divide by two to get your middle number . So let’s do it : 4, 7, 9, 10, 11, 13, 14, 15, 17, 18, 19 Your answer is 13
