Question 1

What are the three types of quantitative data?

Answer 1

1. Discrete - A set of finite data values (e.g. count or score), integers only
2. Continuous - Values in a continuous range (e.g. temperature or height)
3. Nominal - Values represented by labels/names (e.g. 1=good, 2=bad)

Question 2

What are the three types of scales?

Answer 2

1. Ordinal - Number indicates position in a list, ranking
2. Interval - Measurement between values is proportional through the range (e.g. time, ruler)
3. Ration - Ratio between intervals is independent of the unit of measurement or zero point (e.g. floor area ratio)
