Course validity of research depend on (go see definitions on ppt) 1- statistical conclusion validity**this course**= associtation, is there a relationship between two variables? not necessarily causal. Depends on minimizing type i and type 2 errors. much error. = little research for large sample/subject, little error = lots of research on small sample/subject. 2- internal validity**psych 203 (design of the study). Depends on control of confounding factors and invoke principle of ceteris paribus (with other things the same aka changes only with independant variable) 3- construct validity (interpretation of variables, their meanings).
