See the attached file "Example Dependent Samples t-Test (Statistica).doc".



ADDITIONAL MATERIAL
A comparison is made between the results of a Dependent Samples t-Test and a Single Sample t-test on the difference.
See the attached file "Comparison of Dependent Samples t-Test and Single Sample t-Test (Statistica).doc".

An additional comparison is made between the results of the Dependent Samples t-Test and the Independent Samples t-Test.
See the attached file "Comparison of Dependent Samples t-Test and Independent Samples t-Test (Statistica).doc".
