Answer #1

Levels of measurement:

1. Nominal : No ordering

2. Ordinal: Ordering exists - but, not distance

3. Interval: Distance exists - not no zero

4. Ratio: zero exists

(a) Final grades in this class: Ordinal: REASON: The grades are indicators of the qualiy of a student's performanc and are ordered.

(b) Weights of newborn babies: Interval: REASON: Weight of newborn babies cannot be zero. But, differences between values can be computed.

(c) Seasons of the year: Nominal. REASON: Name of season is just a label for the season. There is no order associated with values.

(d) Boiling temperatures of different liquids: Ratio: Boiling temperature can be zero.
