Either select a section to read or read the composite on this page. There are two types of affective tests, quantitative and qualitative.
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 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.
