What is the Difference Between Parametric and Non-Parametric Tests? A parametric test makes assumptions about a population’s parameters, and a non-parametric test does not assume anything about the underlying distribution.

Nonparametric tests offer robustness without strict distribution requirements and are suitable for diverse datasets. A comparison chart demystifies when to use parametric versus nonparametric tests, aligning with data integrity. Real-world case studies illustrate the impactful choice between parametric and nonparametric tests in ...

Les tests non-paramétriques ne se basent pas sur des distributions statistiques. Ils peuvent donc être utilisés même si les conditions de validité des tests paramétriques ne sont pas vérifiées. Les tests paramétriques ont souvent des tests non-paramétriques équivalents.

Choosing a parametric test: regression, comparison, or correlation. Parametric tests usually have stricter requirements than nonparametric tests, and are able to make stronger inferences from the data. They can only be conducted with data that adheres to the common assumptions of statistical tests.

Conduct parametric analysis on both small and large sample sizes, ensuring accurate interpretations. Utilize non-parametric tests such as the Wilcoxon Signed Rank Test, Spearman correlation, and Chi-Square for data sets with ordinal data and non-normally distributed data.

The key difference between parametric and non-parametric tests lies in their fundamental principles and statistical approaches. While parametric tests rely on statistical distributions within the data, nonparametric tests do not depend on any specific distribution.
