median mode mean and range on 84 45 10 28 75 63 16 55
Accepted Solution
A:
PUT THIS SET IN ORDER FROM LEAST TO GREATEST:
10, 16, 28, 45, 55, 63, 75, 84 __________________ MEDIAN: Find the number in the middle of the set. 10, 16, 28, 45, 55, 63, 75, 84 There cannot be two medians, so you find the number between 45 & 55. MEDIAN = 50 _________________ MEAN: Find the average by adding up all of the numbers and dividing them by how many numbers there are. 10 + 16 + 28 + 45 + 55 + 63 + 75 + 84 = 376 376/8 = 47 MEAN = 47 ________________ MODE: The number that occurs most often. If no number repeats, there's no mode. THERE IS NO MODE ________________ RANGE: The difference between the largest and smallest value in the set. Subtract the largest (84) and smallest (10) value. 84 - 10 = 74 RANGE = 74
