What does Statistics mean in a persuasive letter?

Answer 1

Statistics can be used to support a course of action showing, say, how previous cases of something you are proposing was successful.

However, reliance on statistics can backfire as many people will recall the saying that '... there are lies, damned lies and statistics' implying that one can 'prove anything with numbers'.

So, the use of statistics to contributes to a case should, perhaps, be used as supporting evidence and qualified so as to ensure its 'fit' with the case in hand and not the primary evidence
