Mark Twain said, "There are lies, damn lies -- and statistics." This describes a common view about statistics, which is dubious in the extreme about their value.
But the fact that statistics can be, and are, distorted and misused cannot change the fact that they have enormous value. Whenever a prevailing orthodoxy exists, it is clarifying to examine that orthodoxy by some objective method, and statistics are one of the best methods.
A good working knowledge of statistics can also help us to see clearly when others are misusing statistics to gain advantage.
