Very dissatisfied Very satisfied CHAPTER 1: CLASSIFICATION OF DATA, CODING AND DATA ENTRY 1.2 Types of scales d) Ratio Scale • Possesses all the properties of the nominal, ordinal, and interval scales & an absolute zero point • Compute ratios of scale values • y = bx, where b is a positive constant, are allowed All statistical techniques can be applied to ratio data Example: sales, costs, profit, height, weight Level of Measurement Categorical Scale Nominal Finish Numbers Assigned to Runners Finish Ordinal Rank Order of Winners Metric Scale Interval Performance Rating on a to 10 Scale Ratio Time to Finish, in Seconds Third place Second place First place 8.2 9.1 9.6 15.2 14.1 13.4 CHAPTER 1: CLASSIFICATION OF DATA, CODING AND DATA ENTRY 1.3 Coding and data entry Practice with SPSS  - ...
