Nonequivalent group design: a between subjects design with at least 2 groups of participants that uses a subject variable (not manipulated) or that creates groups that are nonequivalent (cid:224) eg. study comparing males & females selects people that are roughly same age and socioeconomic class ( matching"), but since random matching not possible afterwards, groups remain unequivalent: often used when testing effects of brain damage (cid:224) must find brain damaged patients because can"t manipulate this. Analyzing single factor, two level designs: interval or ratio scales (cid:224) 2 types of t test or anova (parametric) t test for independent samples: an inferential statistical analysis used when comparing 2 samples of data in either an independent groups design or an nonequivalent groups design t test for related samples: an inferential statistical analysis used when comparing 2 samples of data in either a matched groups design or a repeated measures design.
