find the median of the data set

82

Step-by-step explanation:

Mean of a set of data is simply the average. It's calculated by adding up all the numbers, then divide by how many numbers there are.

57 + 59 + 64 + 72 + 76 + 77 + 77 + 78 + 85 + 87 + 88 + 88 + 88 + 92 + 94 + 96 + 98 + 100 = 1,476

1476/18 = 82

Therefore 82 is the mean of the set of numbers

Median = 86

Step-by-step explanation:

the middle of the data set is 85 and 87. to find the median you would do 85+87/2= 172/2 median = 86

one set of data has more variation than the other. hope this !

step-by-step explanation:

well if you round, things become much more simple. round 5.95 to 6, 4.25 to 4, and 1.05 to 1. now, add 6+4+1 and that would equal 11. so the items together would equal to about $11.
