Testimonial

I really appreciate your marketing scales database online. It is an important resource for both our students and our researchers as well. Since my copies of the original books are slowly disintegrating due to the intensive use, I am happy that you are making them available in this way. It is very helpful in the search for viable constructs on which to do sound scientific research.

Complexity of the Calculation Task

The scale uses three, nine-point Likert-type items to measure how complicated a person believes a certain task was that involved some degree of mathematical computation.
