Select the statement that is true.

The independent variable is only used in the independent t-test and the dependent variable is only used in the dependent t-test.

The independent t-test is never used in a calculation with more than two groups or sets of data.

Independent means that the independent t-test is not related to any other type of t-test.

The matched pairs t-test will usually have greater variance than the independent t-test when using the same variables.

Answer #1

Since the Independent Samples t Test can only compare the means for two (and only two) groups. It cannot make comparisons among more than two groups. If you wish to compare the means across more than two groups, you will likely want to run an ANOVA.

So the correct statement is

"The independent t-test is never used in a calculation with more than two groups or sets of data."

Statement 1st is wrong since there is no dependent t Test.

Statement 3rd is also wrong because independent means that populations are different.

Statement 4th is also incorrect because we can have the variance less as well.
