Answer:
It is true that statistical methods are no substitute for commonsense. This statement is a caution to the students of statistics. It urges the students not to use statistics devoid of their commonsense.
The statement can be proved true with the help of following story:
Once four persons (husband, wife and two children) set out to cross a river. The father knew the average depth of the river. He also knew the average height of his family members. The average height of two family members was greater than the average depth of the river. So he thought that his family members could cross river safely. But one of the family members (child having less height than the depth of the river), drowned. The fault was not with the statistical method of calculating average but lack of commonsense.
