Question

statistical methods are on substitute for common sense .comments​

Answer 1

Answer:

This is true that Statistical methods are no substitute for common sense. Statistical data should not be believed blindly as it can be misinterpreted or misused. The statistical data may involve personal bias or may undergone manipulations. Also, statistical data and methods fail to reveal the errors committed by an investigator while surveying and collecting data. This can be understood by a story.

It is said that a family of four persons (husband, wife and two children) once set out to cross a river. The father knew the average depth of the river. So he calculated the average height of his family members. Since the average height of his family members was greater than the average depth of the river, he thought they could cross safely. Consequently some members of the family (children) drowned while crossing the river. Thus, the common sense must be used while applying statistical methods.
