Mean = 11 Median = 11 Mode = 4 Range = 18
Mean: 11 Median: 11 Mode: 4 Range: 18
median of {5, 15, 9, 13} is 11 To find the median of a dataset sort the data into order and the median is the middle one; if there are an even number of items in the dataset, then the median is the mean average of the middle two. {5, 15, 9, 13} → {5, 9, 13, 15} There are 4 data items, → median is mean of {9, 13} = (9 + 13) / 2 = 11.
The answer is 8.5

The answer is 8.5
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".
(11/3) - (13/4) = (44/12) - (39/12) = 5/12
The median is 17.5
Median of the set = arithmetic mean of 8 and 9 = 8.5
Divide the four numbers by that 4 when added up 10 + 12 + 14 + 16 = 52 52/4 = 13
