SOC221H5 Study Guide - Final Guide: Design Of Experiments, Internal Validity, Structured Interview
Document Summary
Ex; do observation, introduce something new (treatment), if you see a change between t1 and t2 there is an effect. In other methods causation can be implied or correlation may be the best you will get but here you actually observe causation. High internal validitiy a lot of control over experiment, and flawless design. Easiest method of meeting 3 conditions of causality: temporal order: y always happens before z (time order, association, no alternative explanations. Internal validity: a type of validity that is achieved is there is sufficient evidence that a causal relationship exists between 2 or more variables. External validity: a type of validity that is achieved if the results of a study can be generalizable beyond the specific research context in which they were generated. High degree of control over the setting, artificial setting (lower external validity) Especially true in sociology: we study people in the social world, it does not.
