The mean of the data is 80.
to find the mean of a group of numbers, add them together and divide by the number of numbers there are in that group. in this case there are 6
The range is 72 minus 66 = 6
54, 56, 58, 60, 62, 64, 66, 68, 70, 72
Sort the numbers into numerical order:54, 68, 70, 72, 75, 76, 76, 76, 80, 88, 88, 88, 88, 92, 92, 93The median is the middle number which as there are 16 numbers is the mean of the middle two (highlighted above):median = (76 + 80) ÷ 2 = 78.
76
43

The average is 70.
54, 56, 58, 60, 62, 64, 66, 68, 70, 72
70
Median is 70 The median is the middle number once you have reordered the sequence (therefore, 72 is not the median). The mode is the most common number The mean is the average.
Add up the numbers, then divide by the number of numbers. Answer: 80
Sort the numbers into numerical order:54, 68, 70, 72, 75, 76, 76, 76, 80, 88, 88, 88, 88, 92, 92, 93The median is the middle number which as there are 16 numbers is the mean of the middle two (highlighted above):median = (76 + 80) ÷ 2 = 78.
88
76
71 is the median of those numbers.
