Explanation:
The set of values given represents the ages, in years, of 5 people in a classroom:
We need to identify the outlier.
An outlier is a value within the set that is very different from the rest of the values, it could be very low compared to the rest of the elements or it could be very high compared to the rest of the values.
In this case, from the numbers that we have, we can see that the first four values:
22,23,22,19
are all very close to each other, but the fifth value:
58
is very big compared to the other four values.
Therefore 58 is the outlier.
Answer: 58
