Experimental Questions
Experimental questions are decisive in determining the nature of the experimental design to be selected. There are four basic types of experimental questions: demonstration, comparison, parametric, and component. A demonstration is "Does A cause or influence B?". A comparison is "Does A1 or A2 cause or influence B more?". A parametric question is "How much of A will cause how much change or influence on B?". A component question is "Which part of A{1,2,3} - A1 or A2 or A3... - causes or influences B?" where A is composed of parts which can be separated and tested.
The A-B-A-B design is useful for demonstration questions.

Famous quotes containing the words experimental and/or questions:
“Philosophers of science constantly discuss theories and representation of reality, but say almost nothing about experiment, technology, or the use of knowledge to alter the world. This is odd, because ‘experimental method’ used to be just another name for scientific method.... I hope [to] initiate a Back-to-Bacon movement, in which we attend more seriously to experimental science. Experimentation has a life of its own.”
—Ian Hacking (b. 1936)
“If you think about it seriously, all the questions about the soul and the immortality of the soul and paradise and hell are at bottom only a way of seeing this very simple fact: that every action of ours is passed on to others according to its value, of good or evil, it passes from father to son, from one generation to the next, in a perpetual movement.”
—Antonio Gramsci (1891–1937)
