Web19 sep. 2024 · A Monte Carlo permutation test with 100,000 repetitions comes very close to this value (p = .2122), while a t-test strongly underestimates the exact probability (p = .0629). Throughout this paper, t-tests were conducted with the implicit assumption of equal variances. Therefore, I re-ran all t-tests with the unequal variance option . Web1 sep. 2024 · Conversely, in the nonparametric test, there is no information about the population. The applicability of parametric test is for variables only, whereas nonparametric test applies to both variables and attributes. For measuring the degree of association between two quantitative variables, Pearson’s coefficient of correlation is used in the ...
