Chapter 6 t test for dependent samples Texas A&M University. The two groups were statistically compared using a two sided, independent samples t test with a 0.05 (5%) critical level of significance ( t =2.77, degrees of freedom=334). Which of …, Independent Two Sample T-Test The independent t test evaluates whether the means for two independent groups are significantly different from each other. It is used for just 2 groups of samples. If you have more than 2 groups of samples, you should use ANOVA. For example, if we compare mean salary of male and female employees and check whether there is a statistical significant difference.

If the answer is yes to all three of these questions the dependent sample t-test is the right test, otherwise use the independent sample t-test. In statistical terms the dependent samples t-test requires that the within-group variation, which is a source of measurement errors, can be identified and excluded from the analysis. 9/14/2013 1 Independent Samples t-Test Lecture Set 15 Bivariate Relationships Limits of z-Test and One Sample t-Test? “Univariate only” No manipulation

If you have more than 2 groups of samples, you should use ANOVA. For example, if we compare mean salary of male and female employees and check whether there is a statistical significant difference (See Course Web Page for PDF version.) The two samples are independent. There is no relationship between the individuals in one sample as compared to the other. Both samples are simple random samples from their respective populations. 22 Two Sample t-test Determination of which two-sample t-test to use is dependent upon first testing the variance assumption: Two Sample t-test for

The t-test is used to compare the values of the means from two samples and test whether it is likely that the samples are from populations having different mean values. When two samples are taken from the same population it is very unlikely that the means of the two samples will be identical. Two-Sample t Test In many research situations, it is necessary to test whether the difference between two independent groups of individuals is statistically significant.
