most frequent, will always be at the high point of the distribution
True Experiment
,Give this one a try later!
Every member has an equal chance of selection AND are randomly
assigned to groups. Rare in most studies.
The modern form of describing a hypothesis.
Give this one a try later!
The hypothesis is written in the present tense without the word significant
and without any mention of measurement. You might have sub-hypotheses.
A null hypothesis might include interaction hypotheses.
Parsimony (Occaim's Razor)
Give this one a try later!
The finding should be explained and interprited in the simplest and most
economic way
External validity
Give this one a try later!
Can the findings of this study be generalized to the general population.
, Confounding
Give this one a try later!
When undesirable variable enter the experiment.
Internal threats to validity
Give this one a try later!
Instrumentation, Maturation, Statistical regression, Attrition.
Reliable
Give this one a try later!
If an experiment can be replicated.
Statistical regression
Give this one a try later!
When extreme scores regress to the mean when a test is re-taken.
