During this time it should not be stigmatized but should be used as a time to induce learning: age cannot be manipulated. Quasi experiments: used under conditions where experimentation is not possible, or only partially possible, cant be ised to infer causation as conclusively/comprehensively, but can be useful if, blinding. Quasi vs exptl: why do it the quasi experimental way, 1. Cant expose participants to too many muscle biopsies (within ss version: 2. Logistical constraints on how many participants can be run ( between ss versions) Time series design: rather than assuming before the condition you can measure it before the treatment, helps to empirically establish the natural trajectory of the dv pre- Data trends over time are the focus: multiple dvs measures over time.
