Description Assignment Details Properly classifying the variables that are part of a study is essential to making a correct analysis in SPSS. SPSS classifies variables as nominal, ordinal, or scale and requires you to explain any coding of your data in areas such as the Values column of Variable View. Define the term variables in quantitative analysis. You do not need to explain the differences between dependent and independent variables; instead, focus on the type of data that can be entered for nominal, ordinal, and scale data. What are the key differences between nominal, ordinal, and scale data? Provide an example of each type of data. In what situations could you find each type of data? Why is it important in SPSS that you correctly define the variables in Variable View?
