Exploring Marketing Research William G. Zikmund Chapter 12: Test Marketing
Controlled experimentation Not just trying somethingout But scientific testing Test Marketing
An experimental procedure that provides an opportunity to test a new product or a new marketing plan under realistic market conditions to measure sales or profit potential.

A Lengthy and Costly Procedure $$$$$ Loss of Secrecy When not to Test? How Long Should a Test Last?
Popular Test Markets Pittsfield, Massachusetts Charlotte, North Carolina Columbus, Ohio Little Rock, Arkansas Evansville, Indiana Cedar Rapids, Iowa Eau Claire,Wisconsin Wichita, Kansas Tulsa, Oklahoma Omaha, Nebraska Grand Junction. Colorado Wichita Falls, Texas Odessa-Midland, Texas
Selecting a Test Market Population size Demographic composition Lifestyle considerations Competitive situation Media Self-contained trading area Overused markets - secrecy
Control Method of Test Marketing Small city Low chance of being detected Distribution is forced (guaranteed)
The Advantages of Using the Control Method of Test Marketing Reduced costs Shorter time period needed for reading test market results Increased secrecy from competitors No distraction of company salespeople from regular product lines
Some Problems Estimating Sales Volume Over-attention Unrealistic store conditions Reading competitive environment incorrectly Incorrect volume forecasts –Adjusted data –Penetration and repeat purchase rate Time lapse

Advanced Experimental Designs are More Complex Completely randomized Randomized block design Latin square Factorial
Completely Randomized Design An experimental design that uses a random process to assign subjects (test units) and treatments to investigate the effects of only one independent variable.
Completely Randomized Designs Average minutes shopper spends in store Control: no music Experimental treatment: slow music Experimental treatment: fast music

With a posttest Group ARX 1 O 1 Group BRX 2 O 2 Group CRX 3 O 3 Completely Randomized Design
Randomized Block Design An extension of the completely randomized design in which a single extraneous variable that might affect test units’ response to the treatment has been identified and the effects of this variable are isolated by blocking out its effects.
Independent Variables Control: no music Experimental treatment slow music Experimental treatment: fast music Mornings and afternoons Evening hours Blocking variable Randomized Block Design
Factorial Design An experiment that investigates the interaction of two or more variables on a single dependent variable.

Latin Square Design A balanced, two-way classification scheme that attempts to control or block out the effect of two or more extraneous factors by restricting randomization with respect to the row and column effects.
