Hi
mean = 78.8571 | SUM of scores/number of scores = 1656/21
median = 77 |middle value of the test scores (odd number of scores)
mode = 62 |the most commonly occurring number in this list
range = 36 |(highest - lowest score) = 98 - 62 = 36
62 62 66 68 69 71 72 74 74 76
77
78 79 84 85 87 90 93 94 97 98
