The range is 12 and the standard deviation is 3.822448314.
10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20
The mode is the number which occurs most - so this is 20 The median is the middle number if you write them all in numerical order..... 5, 13, 13, 15, 18, 20, 20, 20 The answer is 16.5 which is in the middle of 15 and 18 To find the mean you add all the numbers up 5+13+13+15+18+20+20+20=124 then divide by the number of numbers in the range (8). 124/8 = 15.5
Mean: 15.5 Median: 16.5 Mode: 20 Range: 15
The median of {10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20] is the 6th values which is 15.
Range = Maximum - Minimum = 20 - 8 = 12.

The median is 20, as it is the middle number when they are all listed in order.
mean = 19.833... median = 19.5 mode = 19
16 + 16 + 16 + 17 + 18 + 18 + 18 + 19 + 19 + 20 + 20 + 20 + 21 = 238
