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.
9
The median is 9.
Mean: 7.875 Median: 7.5 Mode: 14, 6, 8, 1, 9, 5, 7, 13
Re-arrange the numbers in Rank order. Hence. # 5,9,13,14,17. The MEDIAN is the Absolute middle number. which is '13'.
The answer is 8.5
9
Median = 15
The median is 9.
Arrange the numbers in ascending order: 7 9 9 12 13 15 16 and the middle number is the median which is 12
Re-arrange the numbers in Rank order. Hence. # 5,9,13,14,17. The MEDIAN is the Absolute middle number. which is '13'.
11
14, 6, 8, 10, 9, 5, 7, 13 First re-arrange the terms into Rank Order. Hence 5,6,7,8,9,10,13,14. The MEDIAN is the Absolute middle term , which is (9+10) / 2 = 9.5 The MODE is is the most frequent term. As a;; terms occur with the same frequency of one. , then the Median is used as the Mode, Hence 9.5 again. THe MEAN is the sum of all the terms divided by the number of terms. Hence [5+6+7+8+9+10+13+14] / 8 => [72]/8 = 9 The means NB For good measure, the RANGE is 14 - 5 = 9 [

Mean: 7.875 Median: 7.5 Mode: 14, 6, 8, 1, 9, 5, 7, 13
Range: 9 Mean: 12.43 Median: 12 Mode: 9
