can anyone tell a difference between:

  • t-value
  • independent t-value
  • dependent t-value

How to calculate them and when to conduct each test?

you can see Student's t-test at wikipedia. – Argha Oct 7 '12 at 4:57
Could you please supply a reference for these (unusual) terms, "independent t-value" and "dependent t-value"? – whuber♦ Oct 7 '12 at 18:47

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, see the FAQ.

An independent t-test is a test between two unrelated samples and a dependent t-test is a test between two samples when you do expect there to be a relationship between the two.Both tests are used to find significant differences between groups, but the independent samples t-test assumes the groups are not related to each other, while the dependent samples t-test or paired samples t-test assumes the groups are related to each other.

A dependent samples t-test or paired samples t-test would be used to find differences within groups, while the independent samples t-test would be used to find differences between groups.

thanks. Can you also explain how to calculate each t-value and with what value I need to compare them. – Salvador Dali Oct 7 '12 at 11:24
