Mean - 15 ( Add them all together and divide by how many #'s you have. )
Median - 14.5
No mode (mode is number that appears the most)
The median is 9 and the mode is 18 and the mean is 11

Mean: 7 Median: 6 Mode: 6
The mean of those seven numbers is (5 + 9 + 6 + 6 + 11 + 8 + 4)/7 = 7 The median of those seven numbers is 6. The mode of those numbers - the only number which appears more than once - is 6.

Mean: 83 Median: 62 There is no mode.
Mean: add the numbers and divide by how many numbers there are: mean = (13 + 11 + 7 + 4 + 5 + 4 + 8) ÷7 = 52 ÷ 7 = 7 3/7 ≈ 7.429 Median: sort the numbers into order and the median is the one in the middle: {13, 11, 7, 4, 5, 4, 8} → {4, 4, 5, 7, 8, 11, 13} → median = 7 Mode: the most frequent. Using the sorted list from the median calculation, it is easy to see that the number 4 appears twice, but the other numbers only appear once → mode = 4 mode is the only average that does not have to be a number; for example a survey of people's favourite drinks may have one which is more popular than the others, in which case that is the "mode drink".
