Dependent (Paired) Samples t-test


General Notes
 
Also known as the paired-difference t-test.
 
The matched-pairs design is a simple example of a Randomized Block Design (see also Randomized Complete Block Design), where each pair of subjects forms a block. 

See also Repeated Measures ANOVA.
 


Assumptions
 
The observations (here, the differences) are randomly selected from a population distribution that is normally distributed.
