The document discusses scaled and ordinal data. Scaled data can be measured in exact amounts like distances and speeds. Ordinal data provides comparative amounts by ranking items, like the top 3 states in terms of well-being. Examples ask the reader to identify if data is scaled or ordinal, like driving speeds which are scaled, or baby weight percentiles which are ordinal as they compare weights.

- 21. Which 3 monthold babies are in a higher weight percentile nationally - those born in Eastridge or Westridge Hospitals? Scaled? Ordinal?
- 22. Which 3 monthold babies are in a higher weight percentile nationally - those born in Eastridge or Westridge Hospitals? Scaled? Ordinal?
- 23. Which 3 monthold babies are in a higher weight percentile nationally - those born in Eastridge or Westridge Hospitals? Scaled? Ordinal?
- 24. Which 3 monthold babies are in a higher weight percentile nationally - those born in Eastridge or Westridge Hospitals? Scaled? Ordinal? Percentiles provide comparative amounts. In this case, they indicate the percentage of 3 month olds that weigh below the each hospital’s percentage nationally. Let’s say, 3 month olds born in Eastridge hospital are at the 33rd percentile in terms of weight. This means 33% of all 3 month olds born nationally weigh less (a comparison) than those born at Eastridge. Therefore, 67% weigh more.
