Parametric And Non Parametric Tests | PDF } parametric tests make use of information consistent with interval or ratio scale (or continuous) measurement, whereas nonparametric tests typically make use of nominal or ordinal (or categorical) information only. Parametric tests: most of the statistical tests we perform are based on a set of assumptions. when these assumptions are violated the results of the analysis can be misleading or completely erroneous.

Basics Of Non-Parametric Test | PDF | Nonparametric Statistics | Statistics This paper explains, through examples, the application of non parametric methods in hypothesis testing.the model structure of nonparametric models is not specified a priori but is instead. The wilcoxon test provides a nonparametric alternative to a two sample t test or a one way anova for two groups (see chapter 11). it does not assume any particular distribution of the data, except that it is a continuous one (see chapter 6). Non parametric statistics: one and two sample tests nting the population from which the data are drawn. specifica. Do note that non parametric tests make less assumptions, not no assumptions! “a researcher is interested in finding out if there are differences in teenagers’ and young adults’ levels of physical well being (rated 1 100). he recruited 10 teenagers and 10 adults for the experiment.”.

Parametric tests are most powerful for testing the significance. where we can not use the assumptions & conditions of parametric statistical procedures, in such situation we apply non parametric tests. it covers the data techniques that do not rely on data belonging to any particular distribution. Advantages of nonparametric tests used with all scales easier to compute make fewer assumptions need not involve population parameters results may be as exact as parametric procedures. Kruskal wallis test. the kruskal wallis test is a non parametric technique for comparing two or more populations, i.e. analogous to anova. just as in the case of two independent samples the ranks are computed for each observation according to the relative magnitude of the measurements when the data for all the . Nonparametric test due to assumption worries (even with n=42). below is another example paired test where the qq plo looked very bad, but also had a very small sample size, n=15. for this example, the p value in the parametric test was .04934,.
