Restaurant Tipping Summary
This study by Seiter and Gass was titled The Effect of Patriotic Messages on Restaurant Tipping in it the authors compared the effectiveness of 2 types of patriotic messages with a “warmth/ingratiation” message and a control condition on restaurant tipping.
The independent variable in this study was placing one of four messages on customers’ checks: “Have a Nice Day,” “God Bless America,” “United We Stand,” or no message. The servers were instructed to write one of four messages on the back of the checks, representing four experimental conditions: a “warmth/ingratiation” condition, two patriotic conditions, and a control condition. In the “warmth/ingratiation condition”, servers placed a happy-face sticker and wrote “Have a Nice Day.” In the next two conditions, the servers placed an American …show more content…
I would then do a posttest where the restaurant sends out an email survey about the quality of service the customer received and ask questions on how they decided to tip.
Threats to internal validity are hard to prevent. While redoing this experiment you cannot prevent historic events or personal factors of the customers from affecting the results but I do think that you can account for them in some way like surveying feelings of patriotism or how they relate to a job like a server.
I feel that the reliability in the experiment was great in the follow up experiment they could keep the way the dependent variable is measured . They should then open up the experiment to male servers. Also they could test different levels of dining from casual to fine dining and something in between. I feel the results may be different between the three levels.
The follow up study could continue to have a factorial design; an experiment with more than one independent variable level. The follow up experiment could also use the Pretest-Posttest design like I suggested
