Developmental designs/program eval- know when to use each of them in a situation, know 3 types of developmental designs, for program eval. know when to use it and 4 main steps and optional 5th one generally. Prob samp- each member of pop. has speci c prob. of being chosen, necessary if you wanna make speci c statements about speci c pop. on basis of results. Interaction effects allows for the examination of how the relationship if an iv on a dv depends on a second iv, have them with factorial designs and can look at both main and interaction effects. Samp. that involves the pop. being divided into subgroups then random samples being taken from each subgroup is stratified random sampling. Cluster samp. is not /ing pop. into strata but actually having places randomly chosen then randomly picking from within those places. Cohort seq. design has both w/in and b/t subjects variable. Mode can used w/ ratio, interval, or nominal.
