The document discusses different types of data: - Scaled data provides exact amounts like distances and speeds. - Ordinal or ranked data provides comparative amounts by ranking items. - Nominal data names or categorizes items without numerical values. - Nominal proportional data expresses categories as simple percentages. The document uses examples to illustrate each type and provides practice questions for determining the type of outcome data in different scenarios.

- 1. What is the nature of the outcome data? Scaled? Ordinal? Nominal Proportional?Nominal?
- 2. What is the nature of the outcome data? Note: By outcome data we mean, the data that is being influenced by something. For example, “Do humanities or science professors drive faster?” The outcome data is not professors but speed.
- 3. Scaled data provides exact amounts. Central Tendency, Spread, or Symmetry? 12.5 feet60 degrees
- 4. Scaled data provides exact amounts. Central Tendency, Spread, or Symmetry? 80 Miles per hour 12.5 feet60 degrees 1st Place 2nd Place 3rd Place Ordinal or ranked data provides comparative amounts.

- 10. Determine the type of data in each question that follows:
- 11. Does product A or B have the highest profit margin in terms of $$? Scaled? Ordinal? Nominal Proportional?Nominal?
- 12. Does product A or B have the highest profit margin in terms of $$? Scaled? Ordinal? Nominal Proportional?Nominal?
- 13. Does product A or B have the highest profit margin in terms of $$? Scaled? Ordinal? Nominal Proportional?Nominal?
- 14. Does product A or B have the highest profit margin in terms of $$? Scaled? Ordinal? Nominal Proportional?Nominal? Note – even though product A and B are categories and thus nominal, the focus is on what we call the outcome which in this case is $$.
- 15. Does product A or B have the highest profit margin in terms of $$? Scaled data is data that gives you exact amounts. 80 Miles per hour 12.5 feet 60 degrees Scaled? Ordinal? Nominal Proportional?Nominal?
