Outliers are data that are relatively far from other data elements.
The dataset has an outlier and the outlier is 120
The dataset is given as:
- 91 83 84 79 91 93 95 97 97 120 101 105 98
Sort the dataset in ascending order
- 79 83 84 91 91 93 95 97 97 98 101 105 120
The Q1 is then calculated as:
So, we have:
This is the average of the 3rd and the 4th element
The Q3 is then calculated as:
So, we have:
This is the average of the 10th and the 11th element.
The IQR is then calculated as:
Also, we have:
The lower and the upper outlier range are calculated as follows:
120 is greater than 117.5.
Hence, the dataset has an outlier and the outlier is 120

Like terms must have the same variables and those variables must have the same powers.
and
are like terms, because they both have
and they both have
.
and
are NOT like terms, because the powers no longer match.
In your example, do you have the same variables and do the variables have the same powers in both expressions?
