Document Summary
External validity measures the extent to which research findings can be. Generalization across settings: the uniqueness of an experiment makes it possible that the findings are limited to the specific, repeat an experiment. Different operationalizations of the variables: increase the potential generalization by increasing ecological validity, ecological validity (mundane realism) Field experiments experimental research designs conducted in a natural. Replications the process of repeating previous research: exact replications repeat a previous research design as exactly as, conceptual replications investigates the relationship between the. Tests the hypothesis using different operational definitions of same conceptual variables studied in previous research. More systematic and random error possible the independent variable and/or the measured dependent variable construct validity; successful replication boosts confidence in. Failure to replicate casts doubt on the original study"s the validity of the original study"s conclusions: constructive replications tests the same hypothesis as in the. Moderator variable a variable that interacts with the iv.
