MKT 300 Lecture Notes - Lecture 18: External Validity, Internal Validity, Dependent And Independent Variables
Document Summary
Groups are comparable. variables on a single dependent variable. A basic experimental design manipulates only one variable to observe its effects on a. An experimental design that investigates the interaction of two or more independent. Each subject receives every treatment, and the dv is measured for each condition and. Subjects are divided into different groups, and each group is given only one treatment. A situation in which the researcher has more complete control over the research setting. Research projects involving experimental manipulations that are implemented in a natural. The dv is measured for each group and compared. Usually advantageous although they are usually more costly. External validity the accuracy with which experimental results can be generalized beyond the experimental subjects. Artificial laboratory experiments usually are high in internal validity, while naturalistic field experiments generally have less internal validity, but greater external validity. An almost infinite number of variables exists that might conceivably affect a given relationship.
