The functionality of the T.TEST in Excel can be best explained by using an example dataset to get the logic of the T.TEST. I have Group 1 and Group 2 test scores for a classroom. I need to run T.TEST to find a significant difference between these two groups. Apply T.TEST to get ...
What does a two-sample t-test tell you? A two-sample t-test is used to identify whether there is a significant difference in the means of two separate samples. What is the p-value for the t-test? The p-value is a value between 0 and 1 that represents how likely the results could...
In a one-sample t-test, we take a small sample of data from a large population. For example, a small sample of 10 students from a large population of 150 students. The formula then takes the average of a small sample and compares it with the average of the population to check if the...
Describes the different types of t-test for comparing the means of groups. These include: one-sample t-tests, unpaired t-test and paired t-test. One Sample T-Test 10 mins Alboukadel Kassambara Describes the one-sample t-test, which is used to compare the mean of one sample to a know...
We get the result below: What Does the Value Mean? In the example above we have calculated the p-value for the t.test. When conducting hypothesis testing, it is important to set the null and alternative hypothesis. Things to Remember about the T-TEST Function ...

T test formula The formula for the two-sample t test (a.k.a. the Student’s t-test) is shown below. In this formula, t is the t value, x1 and x2 are the means of the two groups being compared, s2 is the pooled standard error of the two groups, and n1 and n2 are the num...
If the absolute value of thet-test statistics(|t|) is greater than the critical value, then the difference is significant. Otherwise it isn’t. Thelevel of significanceor (p-value) corresponds to the risk indicated by thet test tablefor the calculated |t| value. ...
Z and T test results converge as the sample size approaches infinity. Indeed, for sample sizes greater than 30, the differences between the two analyses become small. William Sealy Gosset developed the t test specifically to account for the additional uncertainty associated with smaller samples. Con...
