Paired t-test using Stata Introduction. The paired t-test, also referred to as the paired-samples t-test or dependent t-test, is used to determine whether the mean of a dependent variable (e.g., weight, anxiety level, salary, reaction time, etc.) is the same in two related groups (e.g., two groups of participants that are measured at two different "time points" or who undergo two different. 2ttest— ttests (mean-comparison tests) Menu ttest Statistics >Summaries, tables, and tests >Classical tests of hypotheses >t test (mean-comparison test) ttesti Statistics >Summaries, tables, and tests >Classical tests of hypotheses >t test calculator Description ttest performs ttests on the equality of means. In the first form, ttest tests that varname has. The ttest command performs t-tests for one sample, two samples and paired observations. The single-sample t-test compares the mean of the sample to a given number (which you supply). The independent samples t-test compares the difference in the means from the two groups to a given value (usually 0).

ttest performs t tests on the equality of means. The test can be performed for one sample against a hypothesized population mean. Two-sample tests can be. I don't know of a way to do this with raw data in Stata, but you can do it with Using α, test whether the female mean is greater than the male mean. t-tests are frequently used to test hypotheses about the population mean of a variable. The command to run one is simply ttest, but the syntax. The procedure commonly called t-test, however, refers to a test of the difference between two means (one of which might be a hypothetical. ttest performs t tests on the equality of means. In the first form, ttest tests that varname has a mean of #. In the second form, ttest tests that varname has the same. Note: In Stata 12, you will see that the independent t-test is referred to as the "two -group mean-comparison test", whereas in Stata 13, it is referred to as the "t test. Note: In Stata 12, you will see that the paired t-test is referred to as the "Mean- comparison test, paired data", whereas in Stata 13, it comes under "t test. This population mean is not always known, but is sometimes hypothesized. In this guide, we show you how to carry out a one-sample t-test using Stata, as well . The ttest command performs t-tests for one sample, two samples and paired observations. The single-sample t-test compares the mean of the sample to a given.See This Video: T test means stata
