Question:

Joe Pike is a CMO in a consulting firm out of Miami that specializes in creating loyalty programs for its clients. As a first step, he gathers customer's satisfaction data, and the results for an international hotel chain follow. These data draw form three samples: Brazil, Japan, and England.

Here is the hotelier's response to seeing these data. "Wow, we're doing great in Japan, and pretty good in brazil exp for their perception of value , Maybe the English don't care that much about hotels".
Marketing managers of global multinationals frequently gather customer satisfaction data from their customers all over the world. The question is how to make sense of the data. When the Japanese customer satisfaction ratings look higher than those in England, does that mean the Japanese customers are truly more satisfied, or is something else going on ?
Joe has a lot of experience with international data and known the cross-cultural literature. There are known response tendencies found in different countries These are stereotypes, of course but here are the generalities typical in such data:
Some cultures are said to be "enthusiastic," meaning that the ratings display high variance Tims, customers in the U.S, Brazil (and many other South American countries), France, Italy, and Australia produce data indicating that when customers are happy, they're really happy and that when they're not, they're really most sincerely not.
Other countries, such as England and Germany, are more "reserved." The numbers on surveys show less variability. Ratings tend to be near the midpoint, which means customers won't indicate liking or disliking anything all that strongly.
Some countries (e,g., Japan and some other Asian countries) have an "acquiescence" or courteousness basis, saying things look favorable when maybe deep down that's not quite what they think. Thus, when the Japanese ratings appear more positive, Giving the impression they're happier, it's more likely that they're just being polite on the survey.
How could you tease out the effects of customer satisfaction vs. Cultural biases?
