Step 1: Draw a box plot diagram to show the lowest value, the first quartile, the median, the third quartile and the highest value
From the image drawn, it can be observed that for CPA
A is the least value, B is the first quartile, C is the median, D is the third quartile, while E is the highest value
It can also be observed that for the actuary,
F is the least value, G is the first quartile, H is the median, I is the third quartile, while J is the highest value
It can be observed that the third quartile salary for CPA is between 80 and 90 thousand, say 85 thousand. While the third quartile for actuary is about 90
thousands. It can then be said that it is less than the third quartile for the actuary
Please note that the first quartile is the same as 25%, median same as 50% and the third quartile is the same 75%
Hence, it is less than 75% of the ACTUARY.
