Scale Construction Decisions
- What level of data is involved (nominal, ordinal, interval, or ratio)?
- What will the results be used for?
- Should you use a scale, index, or typology?
- What types of statistical analysis would be useful?
- Should you use a comparative scale or a noncomparative scale?
- How many scale divisions or categories should be used (1 to 10; 1 to 7; −3 to +3)?
- Should there be an odd or even number of divisions? (Odd gives neutral center value; even forces respondents to take a non-neutral position.)
- What should the nature and descriptiveness of the scale labels be?
- What should the physical form or layout of the scale be? (graphic, simple linear, vertical, horizontal)
- Should a response be forced or be left optional?

Famous quotes containing the words scale, construction and/or decisions:
“The Humanity of men and women is inversely proportional to their Numbers. A Crowd is no more human than an Avalanche or a Whirlwind. A rabble of men and women stands lower in the scale of moral and intellectual being than a herd of Swine or of Jackals.”
—Aldous Huxley (1894–1963)
“No construction stiff working overtime takes more stress and straining than we did just to stay high.”
—Gus Van Sant, U.S. screenwriter and director, and Dan Yost. Bob Hughes (Matt Dillon)
“In a minute there is time
For decisions and revisions which a minute will reverse.”
—T.S. (Thomas Stearns)
