Which of the following non parametric tests is the non-parametric alternative to the repeated measures or paired t-test?
Wilcoxon Signed-Rank Test
The Wilcoxon Signed-Rank Test: The Wilcoxon signed-rank Test is a general test to compare distributions in paired samples. This test is usually the preferred alternative to the Paired t-test when the assumptions are not satisfied.
Can you use non parametric tests on continuous data?
Nonparametric tests are suitable for any continuous data, based on ranks of the data values. Because of this, nonparametric tests are independent of the scale and the distribution of the data.
What are the non parametric tests used in place of t test?
The only non parametric test you are likely to come across in elementary stats is the chi-square test. However, there are several others. For example: the Kruskal Willis test is the non parametric alternative to the One way ANOVA and the Mann Whitney is the non parametric alternative to the two sample t test.
When to use a nonparametric instead of a parametric test?
Nonparametric tests serve as an alternative to parametric tests such as T-test or ANOVA that can be employed only if the underlying data satisfies certain criteria and assumptions. Note that nonparametric tests are used as an alternative method to parametric tests, not as their substitutes.
Is there a non-parametric alternative to two-way repeated measures?
I extracted the coherence and the absolute imaginary coherency for all 91 possible connections. As a design for statistical analysis, I chose a two way repeated measures anova.
When to use a nonparametric or one way ANOVA?
The Kruskal-Wallis Test is a nonparametric alternative to the one-way ANOVA. The Kruskal-Wallis test is used to compare more than two independent groups with ordinal data.
When to use a null hypothesis for a nonparametric test?
The null hypothesis for each test is H 0: Data follow a normal distribution versus H 1: Data do not follow a normal distribution. If the test is statistically significant (e.g., p<0.05), then data do not follow a normal distribution, and a nonparametric test is warranted.
