4. Stays the same
Explanation / Answer
Answer-
A. If the largest observation was recorded as 60 instead of 34, the new mean will increase slightly as mean considers summation of all values divided by number of values.
In this boxplot, dot in the right ( outlier) will shift to 60.
B. If the largest observation was recorded as 60 instead of 34, the new median will not be affected as median is the center most value, which will be same after this change.
Boxplot will not change as far as median is considered, only dot in the right ( outlier) will shift to 60.
C. If the largest observation was recorded as 60 instead of 34, the new IQR will not be affected as it is equal to Q3 -Q1 which again are measure of location.
