The mean is the total of all the values, divided by the number of values. To find the mean, we add up all the results and then divide them by the total number of values which is 5:
1 + 1 + 2 + 4 + 7 = 15
15 / 5 = 3.
The median is the middle number in a list of numbers ordered from smallest to largest, so the median is 2.
1, 1, (2), 4, 7
The mode is the value that appears most often in a set of data. In this case, the mode is 1.
1: 2
2: 1
4: 1
7: 1
The range is the difference between the highest value and the lowest value, so the range here is 6.
Highest value: 7
Lowest value: 1
7 - 1 = 6
