Sorry but I don't know the last part of the question.
Answer: mean= 16.9
Median= 14
Step-by-step explanation:
Mean= sum of data set/ number of data set
= 118/7 =16.9
Median- the middle number of a data set, to reflect the best measure of the centre, the data set should be arranged in an ascending order
12, 13, 13, 14, 21, 22,23...... 14 is the median
