Statistical literacy
Most misleading statistics are not fabricated. They are real figures read the wrong way — an average standing in for a distribution, a rise measured from a low point, a correlation quietly promoted to a cause.
This topic covers the small set of concepts that catch most of those errors. None of them require maths beyond arithmetic, and each one is the difference between a number that informs you and a number that flatters whoever published it.
