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
