Can You Do A T Test With Unequal Sample Sizes

Can You Do A T Test With Unequal Sample Sizes - T-tests that assume equal variances of the two populations aren't valid when the two populations have different variances, & it's worse for unequal sample sizes. If the smallest sample size is the one with highest variance the test will have inflated Type I error).

The Welch approximation t-test is designed to do the same thing as an independent samples t-test, but without relying on the assumption that the variances are equal. It is readily available in most standard statistical software. 163 1 1 7 Add a comment 2 Answers Sorted by: 26 Statistical tests do not make assumptions about sample size. There are, of course, differing assumptions with various tests (e.g., normality), but the equality of sample sizes is not one of them.

Can You Do A T Test With Unequal Sample Sizes1 If you only have the two groups you could use the formula interface but you wouldn't want to subset your data first. t.test (age~treat, data=data) should do the same thing. 3 Answers Sorted by 6 t test requires a set of assumptions It assumes your data is i i d independent and identically distributed and comes from a normal distribution If you care to compare the means of the two groups and they follow the assumptions then yes you can use that test

For example, the sample sizes for the "Bias Against Associates of the Obese" case study are shown in Table 15.6.1 15.6. 1. Although the sample sizes were approximately equal, the "Acquaintance Typical" condition had the most subjects. Since n n is used to refer to the sample size of an individual group, designs with unequal sample sizes are ...
