Measurement

Understand . . .

• The distinction between measuring objects, properties, and indicants of properties.

• The similarities and differences between the four scale types used in measurement and when each is used.

• The four major sources of measurement error.

• The criteria for evaluating good measurement.

• “You’re trying too hard to find a correlation here. You don’t know these people, you don’t know what they intended. You try to compile statistics and correlate them to a result that amounts to nothing more than speculation.”

• Marc Racicot, former governor of Montana

• and chairman of the Republican Party

“Initially, many [HR] assessments were used primarily for pre-hire selection; today, assessment providers offer strategic resources for global organizations that want to build their overall knowledge of their employees beyond hiring—for development, promotion, internal mobility and succession planning.”

“The only man who behaved sensibly was

my tailor; he took my measurement anew

every time he saw me, while all the rest

went on with their old measurements and

expected them to fit me.”

George Bernard Shaw

playwright and essayist
