# Levels of Measurement in SPSS Statistics ## Table 1.1 Summary and Comparison of Traditional and SPSS Statistics Terminology for Levels of Measurement | Traditional | SPSS Statistics | Definition | Example | |------------------|-------------------|---------------------------------------------------------|----------------------------| | Categorical | Nominal | General term for nominal and ordinal naming data | Sex: male/female | | | | Ordered data | Highest degree earned | | | Ordinal | | | | Scale | Scale (Continuous)| General term for interval and ratio measurements | Multiple-choice scores | | | | Equal intervals without absolute zero | | | Ratio | | Equal intervals with absolute zero | Weight (in pounds) | ## Variables in SPSS Statistics Researchers use the technical term **variable** to refer to a trait or characteristic that varies among the participants in a study. In SPSS Statistics, you will be identifying categorical variables as either nominal variables or ordinal variables, while interval variables and ratio variables will both be identified as scale variables (see Table 1.1). --- # Exercise for Chapter 1 1. In addition to planning what, whom, when, and how to observe, what else do researchers plan before conducting their research? 2. What are the two primary considerations researchers apply when choosing statistical methods for analyzing a given set of data? 3. The number of correct answers on a multiple-choice math test is at what level of measurement? a. Nominal. b. Ordinal. c. Interval. d. Ratio. 4. Religious affiliation measured by grouping individuals into categories such as Protestant, Catholic, and so on is at what level of measurement? a. Nominal. b. Ordinal. c. Interval. d. Ratio.
