The problem of determining the appropriate statistical method in human and social research

This research aims to find a solution to a problem faced by most researchers in the field of human and social sciences. The problem is related to the use of the appropriate statistical method for analyzing data and testing hypotheses, choosing between the two main types of statistics: parametric and non-parametric. Choosing the statistical method is not random, but rather depends on the fulfillment of certain conditions, such as normality of distribution, sample size, homogeneity, and measurement level (nominal, ordinal, categorical, or relative), the research poses a crucial question: How does a social researcher choose the appropriate statistical method to test the hypotheses of his research?
