3 King Richard (the Lionheart) was king for 10 years. 4 other kings ruled for 21 years, 16 years, 22 years and 31 years. Work out the range, mean, median and mode for how long these 5 kings ruled.

To find the range, we subtract the smallest value from the largest value:
Range = 31 - 10 = 21
To find the mean, we add up all the values and divide by the total number of values:
Mean = (10 + 21 + 16 + 22 + 31) ÷ 5 = 20
To find the median, we need to arrange the values in order from smallest to largest:
10, 16, 21, 22, 31
The median is the middle value when the values are arranged in order. Since there are an odd number of values, the median is the middle value of the sequence, which is 21.
To find the mode, we need to find the value that occurs most frequently in the sequence. In this case, there is no mode because no value occurs more than once in the sequence.
