You would like to assess how good your measures are. Which one of the following would be the least likely technique to use? Sensitivity Validity Scalability Reliability
Scalability
diagnostic analysis
Seeks to diagnose reasons for market outcomes and focuses specifically on the beliefs and feelings consumers have about and toward competing products.
Manipulation of the Independent Variable
Several experimental treatment levels (different values of the independent) may be used. More than one independent variable may be examined.
Systematic or nonsampling error
Subject selection, experimental design, and unrecognized extraneous variables
constancy of conditions
Subjects in all experimental groups are exposed to identical conditions except for the differing experimental treatments.
External validity
The accuracy with which experimental results can be generalized beyond the experimental subjects Student Surrogates = Atypical?
Main Effect
The experimental difference in dependent variable means between the different levels of any single experimental variable.
Internal Validity
The extent that an experimental variable is truly responsible for any variance in the dependent variable. --does the manipulation truly cause changes in the specific outcome of interest?
