Basic terminology: factor, differentiates between a set of groups being compared in an experiment. Drug administration: condition, (cid:862)how is the group treated i(cid:374) a(cid:374) experi(cid:373)e(cid:374)t? (cid:863) Handled for 10 minutes & given 10mg of drug. Not handled & given 10 mg of drug. Levels: different values of the independent variable that are selected to create the treatment condition. Animal handling: handling vs. no handling of animals, handling for 10, 20, 30 minutes. Drug administration: drug dosage: 10, 30, 100 mg of drug, time course: 1,2,3, 4 hrs. Characteristics of a variable: observable can be measured directly or indirectly, replicable can be consistently measured. **in order for the above to be true = must be specific & unambiguous: must have at least 2 levels/ values. Types of variables: situational variables, describes characteristics of a situation or environment. What aspect of the environment changes for the subjects: most experimentally manipulated variables are in this category.
