As we all have learned over unit seven, a t test is a hypothesis testing tool used to test an assumption of a specific population. Along with most tests, there are some drawbacks, or limitations, to t tests. One limitation of a t test is the carry over effects (“Pros and Cons of T-Test”, 2019). There are problems that go along with repeated measures instead of differences between group designs, which leads to carry over effects. Another limitation with t tests is that they cannot be used for multiple comparisons. If a t test is used for multiple comparisons, type one errors will result. As a refresher, type one errors happen when we reject a true null hypothesis (“Pros and Cons of T-Test”, 2019). As we have learned, type one errors can cause very big mistakes. With that being said, it will be nearly impossible to ever reject the null hypothesis. While there are more limitations to t tests, there are also many benefits. Before using a t test, all factors should be weighed to determine the best option. Overall, the test used will depend on what we are looking for and the data given.

This week’s discussion topic is the types of t-test. Those three types of the t-test are as follows independent samples t-test, paired sample t-test, and one sample t-test The first t-test t is an independent sample t-test .which is also known as the unpaired samples t-test as well as the most commonly used. (Urban,2005). When using the independent sample t-test you will need to compare the means for two groups. As an example, we would use this test to get the average scores of males and females on a height test. This test will tell us if there is a difference between the two groups. The second t-test is the paired sample t-test which is also known as a correlated pairs t-test, a paired samples t-test as well as a dependent samples t-test (Urban,2005)this type of t-test may be used for comparing means from the same group but at different times, such as time, year, date, etc. (Urban,2005). AS an example, we could use this test to see if there is a difference in cost for dentures between two different dentures’ specialist facilities. The third type of t-test is the one-sample t-test can be used when testing the means from one group to a known mean. As an example, by using this type of t-test somebody may want to know the sample mean so they compare it to the population mean. By using this test would definitely be appropriate use especially when you don’t know the population’s standard deviation and or if the sample size is a small scale.
