Explanation / Answer

1) arranging the data in ascending order

2, 3 , 4 , 4 , 6 , 6 , 5 , 5 , 6 , 7 , 7, 8 , 9 , 18

total numbers = 14

mean = 2+ 3 + 4 + 4 + 6 + 6 + 5 + 5 + 6 + 7 + 7+ 8 + 9 + 18 / 14

mean = 6.42857

median = (6+6)/2 = 6

mode = 6

2) score on 10 quizzes

5 , 8 , 3 , 9, 9 , 9 , 9 , 9 , 7 , 10

avearge = ( 5+8 + 3 + 9+9+9+9+9 +7 +10 ) / 10 = 7.8

so , average score = 7.8

so he claimed wrong
