is a likert survey parametric can a parametric testing test use a likert scale when a sample size is small what parametric testing is used which of the following is the most appropriate test for small data? which parametric test is the best what is the difference between parametric and nonparametric why use a parametric testing tool what tests are used in the likert scale when to use parametric test or non-parametric test are parametric tests valid which parametric test do i use? why parametric test not used can a parametric test be nonparametric when do you use a parametric or non parametric test when to use parametric test should you use a parametric or nonparametric which test is parametric or nonparametric what is the difference in parametric and nonparametric when you have a parametric test should you use a parametric test are kolmogorov smirnov tests parametric
