A child psychologist is developing an instrument designed to measure the social etiquette of small children. The instrument includes 25 statements; for example, “wishes elders when they meet them,” “courteous to their sibling,” and “says please when asking for something or thank you when someone has helped.” Parents must rate each of these statements on a 5-point scale as follows:
0 never
1 rarely
2 sometimes
3 often
4 always
Parents who answer “never” to each of the 25 questions get the lowest possible score of 0 on the instrument. Parents who answer “always” to each of the 25 questions get the highest possible score of 100 on the instrument. Thus, scores on the instrument range from 0 to 100. What kind of scale do the scores represent?
