The Mann-Whitney U test is a non-parametric statistical test used to determine whether there is a significant difference between the distributions of two independent samples. It assesses whether one sample tends to have larger values than the other, without assuming a normal distribution. The test ranks all the data points from both groups and calculates a U statistic based on these ranks. It's often used when the sample sizes are small or when the data violate the assumptions of parametric tests like the t-test.

What is an example of a non parametric test?
An example of a non-parametric test is the Mann-Whitney U test, which is used to compare two independent groups when the data do not necessarily follow a normal distribution. Unlike parametric tests that assume a specific distribution for the data, non-parametric tests are more flexible and can be applied to ordinal data or non-normally distributed interval data. The Mann-Whitney U test evaluates whether the ranks of the two groups differ significantly.
Which conditions must be met to conduct a test for the difference in two sample means?
The two samples must be independent and the data must be at least ordinal. Under those conditions the Mann-Whitney U test can be used.
How do you write statistical conclusion to mann Whitney test?
The Mann-Whitney is a test that two populations have the same location. As with other statistics, the ultimate result of the test can be quoted as a significance level. In most literature it suffices to indicate either which of the so-called 'standard' levels (0.01 or 0.05) the result exceeded (if it did) or the actual calculated significance level. If M-W shows significant difference then you can discuss the meaning of the difference in location or central tendencybetween the two populations you have considered.

What are the example of inferential statistics?
Mean, variance, t-statistic, z-score, chi-squared statistic, F-statistic, Mann-Whitney U, Wilcoxon W, Pearson's correlation and so on.
What statistical test should be used to determine if the average scores of two independent groups?
To determine if the average scores of two independent groups are significantly different, you should use an independent samples t-test. This test compares the means of the two groups and assesses whether any observed difference is statistically significant. It assumes that the data is normally distributed and that the variances of the two groups are equal (or approximately so). If the assumptions are not met, a non-parametric alternative, such as the Mann-Whitney U test, can be used.
What type of tests can be used if the assumptions of normalcy are not met?
If the assumptions of normality are not met, non-parametric tests can be used as alternatives to traditional parametric tests. Examples include the Mann-Whitney U test for comparing two independent groups, the Wilcoxon signed-rank test for paired samples, and the Kruskal-Wallis test for comparing more than two independent groups. These tests do not require the data to follow a normal distribution and are based on ranks rather than raw data values.
How do you Set up a nonparametric test using the six-step hypothesis testing procedure?
To set up a nonparametric test using the six-step hypothesis testing procedure, start by stating the null hypothesis (H0) and the alternative hypothesis (H1). Next, select the appropriate nonparametric test based on the data type and research question, such as the Mann-Whitney U test or the Kruskal-Wallis test. Then, determine the significance level (alpha), typically set at 0.05. Collect the data, perform the test to calculate the test statistic, and finally, compare the p-value to the significance level to make a decision about the null hypothesis.
