|---|---|
 Paired samples | each case in one sample corresponds to a particular case in other sample eg repeated measures design |
| Independent samples | cases in each sample are completely independent eg between-group design |
| p - value is | the probability of obtaining a test statistic as deviant as the one obtained, under H0 (ie when H0 is true) |
| Recall that a large t statistic does not | necessarily imply that the detected effect is large or functionally important |
| Likewise, a small Sig/p value (e.g., p < 0.001 of obtaining a |t| larger than the one you have) also | does not necessarily imply that the detected effect is large or functionally important |
| "natural pairs" | the researcher does not randomly allocate participants to one group or another; the pairing occurs "naturally" prior to the study although the pairs are made up of different participants the scores of each pair are likely to be correlated --> dependent means analysis |
| "matched pairs" | the researcher has control over the ways the pairs are formed so that participants are matched on some variable although the pairs are made up of different participants the scores of each pair are correlated--> dependent means analysis |
