Non-parametric statistics are a set of statistical methods that do not make any assumptions about the underlying distribution of the data. One such non-parametric test is the Kruskal-Wallis test, which is used to compare three or more independent groups when the dependent variable is ordinal or continuous but not normally distributed.

Non-parametric statistics offer a valuable alternative for researchers when certain assumptions of parametric approaches are not met. One common non-parametric test is the Wilcoxon Signed-Rank Test, which is used to compare two paired groups. This test is particularly useful when the data is not normally distributed or when the data is ordinal.

Factor analysis is a powerful multivariate statistical technique that can help researchers uncover underlying relationships among variables. By examining how a set of observed variables are related to a smaller number of latent factors, factor analysis can provide valuable insights into the structure of data, reduce complexity, and aid in understanding the underlying dimensions influencing the observed correlations.

Experimental design is a fundamental aspect of scientific research, helping researchers to carefully plan and conduct experiments in order to obtain meaningful and reliable results. One important technique used in experimental design is factor analysis, which involves studying the relationships between variables to identify underlying factors that may be influencing the outcomes of an experiment.

Randomized controlled trials (RCTs) are a powerful tool used in experimental design to test the effectiveness of an intervention or treatment. This type of study design is considered the gold standard for evaluating the efficacy of new medical treatments, therapies, or interventions. In an RCT, participants are randomly assigned to either the treatment group or the control group, which allows researchers to compare the outcomes between the two groups and determine the impact of the intervention.

Correlation analysis is a statistical technique used to measure the strength and direction of the relationship between two variables. Partial correlation analysis, on the other hand, is a more advanced method that allows us to explore the relationship between two variables while controlling for the influence of one or more additional variables.
