Question

1) We have studied several types of common but faulty statistical reasoning (violation of the
area principle, supposing that correlation implies causation, etc.) and limitations of
testing (sample bias, errors in hypothesis testing, etc.). Find TWO examples of these
flaws/errors in advertisements, news articles, or research papers. Give the source (url or
other citation). Explain the mistake in each, and explain what might be done differently to
correct the mistake.
