Dependent and independent samples

What is actually the difference between a dependent sample and an independent sample (paired or unpaired samples)? And why is it important to know the difference? Whether the data are from a dependent or independent sample determines which hypothesis test is used.
If your data are independent, for example, a t-test for independent samples is calculated or an analysis of variance without repeated measures. If your data are dependent, for example, a t-test for dependent samples or an ANOVA with measurement repetitions is calculated.

Being a dependent is always better in a real world. Dependency all the way! It makes my life alot easier! :)

Thank you. Very nicely explained. In the 3:51 minute, when you talk about dependent samples and the machines lubricated, is it the same machine being lubricated first with great A and than with grease B, or are there two machines of the same type?

Excellent. I have a question please. If I have multiple measurements of a single variable of two different times taken at the same points with coordinates. This would be considered a related or dependent sample, right?

[@datatab]

Yes I think so!

Could you please tell me parametric test that can be used for trend analysis. I want to use it to identify trend in hydrochemical data that include concentrations of Ca, Mg, Na, etc.

[@larissacury7714]
