Document Summary

Good research is valid, meaning that the conclusions drawn by the researcher are legitimate. 4 major types of threats to the validity of research: It is claimed that the measured variables or the experimental manipulations relate to the conceptual variables of interest when they actually may not. 2. research may be incorrect because a type 1 or type 2 error was made. Threats to internal validity: it is claimed that the independent variable caused the dependent variable, but the dependent variable may have actually been caused by a confounding variable. 4. general, but the observed effects may only be found under limited conditions or for specific groups of people. Threats to external validity: it is claimed that the results are more. An important aspect of a good experiment is that it has experimental control, which occurs to the extent that the experimenter is able to eliminate effects on the dependent variable other than the effects of the independent variable.
