equal. Numeric: Numeric variables as you might expect, have data values that are recognized as numbers. Use this variable for both integer and decimal number (dot used to indicate decimals, not comma). String: also called alphanumeric variables, have values that are treated as text VARIABLE TYPE
labels up to 256 characters. Variable labels can contain spaces and reserved characters that are not allowed in variable names. Do yourself a favor: everytime you create a dataset, make sure to describe what each variable is/means using the Label field. VARIABLES LABEL
treated as scale when its values represent ordered categories with a meaningful metric, so that distance comparisons between values are appropriate. Examples of scale variables include age in years, and income in thousands of Dollars. VARIABLES MEASURE
treated as ordinal when its values represent categories with some intrinsic ranking. For example, levels of service satisfaction from highly dissatisfied to highly satisfied. Examples of ordinal variables include a degree of satisfaction among the consumers, school grades (A, B, C, D, E, F), etc. VARIABLES MEASURE
treated as nominal when its values represent categories with no intrinsic ranking. For example the department of the company in which an employee works. Examples of nominal variables include region, zip code, or gender of individual or religious affiliation. VARIABLES MEASURE
variable independent, meaning that they cannot be ranked? If yes, it’s Nominal. Example: First name, Nationality, University name. Do the values of a variable share all the same unit of measurement, and they can be ordered? If yes, it’s a Scale. Examples include Height (cm or ft, in), Age (in years), speed (in km/h), weight (in kg, pounds)... Can the values of a variable be ordered according to some meaningful principle and values do not share a common unit of measurement? If yes, it’s ordinal. Examples include school grades (A, B, C, D, E, F), experience (beginner, intermediate, expert), etc. VARIABLES MEASURE: RULE OF THUMB
