There are six numbers, so the median is the mean of the third and fourth (when ordered).
Median = (14+27)/2 = 41/2 = 20.5
The median of the numbers 10 12 13 17 17 18 27 is 17.
First of all rearrange the numbers in Rank order. Hence 17,13,12,18,17,10,27 becomes. 10,12,13,17,17,18,27 The MEDIAN is the absolute middle term. Which is '17'. The MODE is the term which occurs most frequently. 17 appears twice, all the rest only appear once. Hence '17' is the mode. The MEAN is the sum of all the te rms divided by the number of terms. [10+12+13+17+17+18+27] / 7 = 114/7 = 16 2/7 = 16.2857 (4 dp_ is the Mean The RANGE is the difference between the greatest ad least terms. 27 - 19 = 17 is the Range.
Median = (18+27)/2 = 22.5
14. Put in order: {1, 6, 10, 12, 12, 13, 15, 19, 27, 31, 32, 40} There are 12 data items, so the median is the (12 + 1) ÷ 2 = 61/2th data item. As 61/2 is not a whole number, take the mean average of the 6th and 7th data items: 6th is 13, 7th is 15 ⇒ median = (13 + 15) ÷ 2 = 14

The median is 20, as it is the middle number when they are all listed in order.
