All the numbers have the same frequency (in this case 1), so there is no mode [average].
Mode refers to the most commonly recurring number. In this case, both 68 and 70 appear twice. So, this set has two modes.
The mode is 68.
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.
55, as it appears more than any other number in the list.
68, because it appears more than any other number.
43
70
68 multiplied by 68 is 4,624.
The average is 70.
It is: 0.70*68 = 47.6
The range is 72 minus 66 = 6
71 is the median of those numbers.
