BRAINIEST TO WHOEVER RIGHT NOW PLZ. I NEED IT DONE NOW

Answer:
21.
Step-by-step explanation:
An outlier is basically a data point that is just significantly different from other data values (way higher or way lower.)
However, you can see that most of the data points range in the 50-70 points, except the 21. Therefore, it is an outlier.
Answer:
The outlier will be 21.
Step-by-step explanation:
As we can see, most of the points are in the 50, 60, 70 range.
There are none in 30 nor 40.
21 is far away from the 50, 60, 70 range (where most points are), so therefore, it is an outlier.
