The Null Hypothesis

• Modus Tollens
• The Logic of the Null Hypothesis
• Modus tollens (Latin mode that denies) is the
  formal name for indirect proof or proof by
  contrapositive (contrapositive inference), often
  abbreviated to MT. It can also be referred to as
  denying the consequent, and is a valid form of
  argument (unlike similarly-named but invalid
  arguments such as affirming the consequent or
  denying the antecedent).
