would like to calculate the p-value that the means are equal. .svy: mean y .svy: mean y, subpop(Michigan_dummy) Is there a post-estimation test that can compare the survey-based means above? I've also thought of the following, but both compare Michigan to non-Michigan states (not t...

Out of the 166 articles published in Journal of Industrial Microbiology and Biotechnology (JIMB) in 2019–2020 (not including special issues or review articles), 51 of them used a statistical test to compare two or more means. The most popular test was the (Standard) t-test, which often ...
The choice of statistical test depends on your research design, the type of data you have, and the hypotheses you’re testing. Some of the most commonly used statistical tests include: t-Test:Used to compare the means of two groups. There are two types: independent samples t-test (for c...
If we have repeated measurements by each of two methods on the same subjects we can calculate the mean for each method on each subject and use these pairs of means to compare the two methods using the analysis for assessing agreement described above. The estimate of bias will be unaffected,...
Wilcoxon rank test (non-parametric) Comparing the means of more than two groups ANOVA test (analysis of variance, parametric): extension of t-test to compare more than two groups. Kruskal-Wallis rank sum test (non-parametric): extension of Wilcoxon rank test to compare more than two groups...
T-test One of the most common statistical tests is the t-test, which is used to compare the means of two groups (e.g. the average heights of men and women). You can use the t-test when you are not aware of the population parameters (mean and standard deviation). ...
