Question

In Prof. Johnson's class, the 10 students had the following scores on the last midterm.

Answer 1

Answer: 188 is the outlier

Step-by-step explanation:

Find median of the whole data set. The median is 83.5.

Then find Q1 and Q3. Q1 is 78, Q2 is 96.

Then find the IQR. The IQR is 18.

Find the inner fences of the data set. The inner fences are 51 and 123. Anything that is outside of 51 or 123 is an outlier so 188 is an outlier.
