  • Nonparametric Statistics & Hypotheses Examples

    Nonparametric statistics use tests of significance that do not require normal distribution or interval level of measurement. As such, these tests can be used with ordinal or nominal data (i.e., data that is classified rather than ranked).

  • Chi Square

    Such data cannot, on any logical basis, be ordered numerically, hence there is no possibility of using parametric statistical tests which require numerical data.
