• Explain analysis of variance, multivariate statistics

  These nonparametric tests often are more powerful in detecting population differences when certain assumptions are not satisfied. All tests involving ranked data, i.e. data that can be put in order, are nonparametric.

• Parametric and Nonparametric tests

  The use of non-parametric methods may be necessary when data have a ranking but no clear numerical interpretation, such as when assessing preferences; in terms of levels of measurement, for data on an ordinal scale.

• Hypothesis Testing - Parametric and Nonparametric Statistics

  How are parametric and nonparametric statistics similar? Many non-parametric tests are based on ranked data.

• 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).

• Usage of ANOVA, Non-Parametric tests

  If this is not possible to do (lack of resources, time...) then questions should be tailored to fit the nonparametric best practice: Many nonparametric procedures are based on ranked data.

• When would one use nonparametric tests at their place of employment, in education, or in politics?

  An alternative approach does not assume that data follow a Gaussian distribution. In this approach, values are ranked from low to high and the analyses are based on the distribution of ranks.

• Distribution Free vs. Non-Parametric

  (Distribution-free methods are the opposite of parametric methods.) This category includes nonparametric methods. * Non-parametric statistical methods make no assumptions about the probability distribution of the data.
