QUALITATIVE VS. QUANTITATIVE TESTING:

There are two types of affective tests, quantitative and qualitative. Qualitative tests measure subjective responses of a sample of consumers to the sensory properties of products by having them talk about their feelings in an interview or group setting (Meilgaard 1991). Quantitative tests determine the responses of a large group of consumers to a set of questions regarding preference (Meilgaard 1991).

Quantitative testing tends to be more popular for a number of different reasons. Quantitative testing allows the researcher to gain much more data and information in a much shorter amount of time than qualitative testing allows. It is also far less expensive to test quantitatively. But most important is the fact that this style of testing allows the researcher to ask the very specific questions, and in most cases only allow the consumer choose their response from a given list of answers. This allows the researcher to pinpoint certain areas he or she would like to concentrate on. This is much more accurate than wading through written responses from quantitative tests and relying the researchers own judgment as to what the consumer really meant in their answer. A well written quantitative test can produce deadly accurate data with little or no variables to allow the results to be tainted. Once testing is complete, the data can be analyzed and graphed for easy study and finally the company has a solid feel for whatever it was that they were testing.
