Nonparametric Tests . Nonparametric tests are those that do not rely on probability distributions for population parameters They are used when Data are badly skewed Sample sizes are small Data are not on an interval or ratio scale . Chi-Square and Goodness of Fit Test.
Nonparametric Tests. Chapter 11. Elementary Statistics Larson Farber. Section 11.1. The Sign Test. Nonparametric Tests.
Nonparametric Tests. Underlying population distribution is continuous. No other assumptions. Data need not be quantitative, but may be categorical or rank data. Very quick and easy to perform. Parametric vs. Nonparametric.
Nonparametric Tests. February 2013. Nonparametric Tests. Nature of the distribution is not known, or known to be non-normal. Sometimes called distribution free statistics Everything up to this point we’ve assumed comes from data that IS normally distributed. Nonparametric Tests.
Chapter 11. Nonparametric Tests. The Sign Test. § 11.1. Sign Test for a Population Median. A nonparametric test is a hypothesis test that does not require any specific conditions concerning the shape of the population or the value of any population parameters.
