SPSS: Changing scale variable to nominal variableData collection rating scales; Nominal data collection does not include rating scales, which is very common with ordinal data collection. Examples: grade in school, position in race, rating scales. The Chi-Square Test of Independence determines whether there is an association between categorical variables (i. The simple answer is that Likert scales are always ordinal. In scientific research, a variable is anything that can take on different values across your data set (e. Interval Scale. The ordinal scale does not assume that the distances from 0 to 1 and 1 to 2 (and so on) are equal. The typical situation of using correlation analysis is when both X and Y are continuous variables or scales in SPSS sense (either interval or ratio data ). The two most common types of statistical measures are those for central tendency and those for dispersion. Changes variable names.

Even though these are numbers, they do not imply an order, and the distance between them is not meaningful. SPSS will not stop you from using a continuous variable as a splitting variable, but it is a bad idea to try to attempt this; SPSS will see each unique numeric value as a distinct category. Abebe Tilahun Kassaye. An ordinal variable contains values that can be ordered like ranks and scores. Nominal scale data are not ordered.

Ratio: exactly the same as the interval scale except that the zero on the scale means: does not exist. A discrete–ordinal scale is a nominal variable, but the different states are ordered in a meaningful sequence.
