Question

9 multiple choice 10 points the number of minutes that it has taken you to complete this quiz thus far would be considered a/an ____ level of measurement. nominal ordinal interval/ratio none of the above. 10 multiple choice 10 points the perceived level of difficulty of this quiz (ranked not difficult, moderately difficult or very difficult) would be considered a/an ____ level of measurement. nominal ordinal interval/ratio none of the above

Explanation:

Question 9

1. Recall the levels of measurement:

• Nominal: Categories with no order (e.g., gender, eye color).
• Ordinal: Categories with order but no equal interval (e.g., rankings like 1st, 2nd).
• Interval/Ratio: Has equal intervals and a true zero (e.g., time, weight, height).

1. The number of minutes to complete the quiz has a true zero (0 minutes means no time spent) and equal intervals (1 minute is the same unit everywhere). So it's interval/ratio.

1. Recall the levels of measurement:

• Nominal: Categories with no order.
• Ordinal: Categories with order (ranking) but no equal interval between them (e.g., difficulty levels: not difficult, moderately difficult, very difficult – there's an order but the difference between "not difficult" and "moderately difficult" isn't a fixed interval like in interval/ratio).
• Interval/Ratio: Requires equal intervals and true zero, which difficulty levels don't have.

1. The perceived difficulty is ranked (ordered), so it's ordinal.

Answer:

C. interval/ratio
