Solution
For this case we can see that the best answer is:
Low
Since we have overlap just in some values representing a low percentage of all the datasets
For the second case we have the following dataset:
27 28 28 29 29 29 30 30 30 31 31 31 33 34
We have 14 values then we can find the median like this:
Median = (30+30)/2= 30
