Hey there!
An outlier in a data set is a number that is WAY larger or WAY smaller than the others in the data set, or does not really fit in the specified "range". In the first one, 452 is way greater than everything else, so it would be the outlier.
In the second data set, 5 would be our outlier because it is much smaller than all the other numbers.
In the last data set, the numbers are pretty close together, but we need to find one that isn't inside the small range. 0.201 appears to be the outlier in this case.
Therefore, here are your answers :)
15: 452
16: 5
17: 0.201
I hope this helps!
