Document Summary

External validity: how well do your findings generalize across situations, people, manipulations, etc. Internal validity = easier to attain in the lab: control, external validity = easier to attain in the field, generalizability! Internal: goal is to draw a confident causal conclusion-- internal validity! Ideally, hypothesis tested in both lab and field. One-way designs: one independent variable, could be any amount of levels , condition assignment. Factor = iv: >2 iv with each >2 levels. Factorial nomenclature : 2 iv and 2 levels each 2x2 factorial design, __x__ where, # of blanks = # of ivs, value itself = # of levels of that iv. Iv2 = presence of others (alone, group: dv = stress. Issues with opting for: btn subjects, much more participants (6x as many as within subjects design, within subjects, less participants but there are carry-over effects and order effects, neither is ideal!
