Quantitative research is a systematic investigation that primarily focuses on quantifying relationships, behaviors, and phenomena through statistical, mathematical, or computational techniques. It plays a crucial role in various fields by providing objective data to support decision-making and policy formulation.

Read MoreProbability: Bayes’ TheoremNon-parametric methods in statistics refer to techniques that do not assume a specific distribution for the data, making them particularly useful for analyzing ordinal data or when sample sizes are small. These methods include tests such as the Wilcoxon signed-rank test and the Kruskal-Wallis test, which are robust alternatives to their parametric counterparts.
