Document Summary
Chapter 10: categories of inference and validity type. Construct validity: are the constructs that are claimed to be studied, in fact, what they are truly being manipulated and measuring. Statistical validity: involves proper stat treatment of data and soundness of researcher"s stat conclusions. Internal validity: degree to which a researcher is certain that a certain variable has a causal effect on another. External validity: degree to which a study"s results can be generalized to other situations than the one in which they were obtained. Statistical conclusion validity: did researchers perform appropriate stat analysis/does data meet assumptions surrounding particular tests. External validity: can findings be generalized beyond he present study to other populations/settings/species? (ie not just uni students in psyc 100 forced for credit) ?, things done in naturalistic observation has more ecological validity than lab research) Mundane realism: addresses similarity b/w experimental environ and real world settings (read news paper article=more mundane, rather than memorize random letter combinations_
