What is the difference between independent samples t-test and dependent samples t-test?
Dependent samples are paired measurements for one set of items. Independent samples are measurements made on two different sets of items. If the values in one sample affect the values in the other sample, then the samples are dependent.
Why are dependent samples t tests valuable?
The major advantage of choosing a repeated-measures design (and therefore, running a dependent t-test) is that you get to eliminate the individual differences that occur between participants – the concept that no two people are the same – and this increases the power of the test.
What is the test used to check the dependency between observations?
It is also called the paired t-test, because measurements from one group must be paired with measurements from the other group. The dependent sample t-test is used when the observations or cases in one sample are linked with the cases in the other sample.
