What is an independent samples t-test?
- The Independent Samples t Test analyzes the means of two separate groups to see if there is statistical support that the population means values are statistically substantially different.
- A parametric test is the Independent Samples t Test.
- The Independent t Test is another name for this test.
- When you wish to compare the means of just two groups—no more, no less—use an independent samples t-test! This test is typically used to detect whether two population means differ.
- For instance, you could determine whether first-year graduate salary varied by gender using an independent t-test (i.e., your dependent variable would be "first-year graduate salaries" and your independent variable would be "gender", which has two groups: "male" and "female").
