## Is age a scale variable in SPSS?

A variable can be 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 Rupees, or score of a student in GRE exam.

**What is the difference between scale and ordinal in SPSS?**

In summary, nominal variables are used to “name,” or label a series of values. Ordinal scales provide good information about the order of choices, such as in a customer satisfaction survey. Interval scales give us the order of values + the ability to quantify the difference between each one.

**What does scale ordinal and nominal mean in SPSS?**

Nominal scale is a naming scale, where variables are simply “named” or labeled, with no specific order. Ordinal scale has all its variables in a specific order, beyond just naming them. Interval scale offers labels, order, as well as, a specific interval between each of its variable options.

### What does scale mean in statistics?

Scales of measurement refer to ways in which variables/numbers are defined and categorized. Each scale of measurement has certain properties which in turn determines the appropriateness for use of certain statistical analyses. The four scales of measurement are nominal, ordinal, interval, and ratio.

**What is a scale variable?**

Essentially, a scale variable is a measurement variable — a variable that has a numeric value. This could be an issue if you’ve assigned numbers to represent categories, so you should define each variable within the measurement area individually.

**Is age scale ordinal or nominal?**

Age can be both nominal and ordinal data depending on the question types. I.e “How old are you” is a used to collect nominal data while “Are you the first born or What position are you in your family” is used to collect ordinal data. Age becomes ordinal data when there’s some sort of order to it.

## What does the meter scale mean in SPSS?

In SPSS, for all practical purposes, it combines the Interval and Ratio scale into one and called Scale variable. We can see the meter scale kind of symbol for the scale variable, so it is showing that it’s a quantitative variable. However, the quantitative variables are either interval variables or ratio variables.

**Why do we need a categorical scale in SPSS?**

The Categorical scale is also known as Discrete scales. So we need a categorical scale to measure the categorical variable. The categorical variable comes into two formats as Nominal variables and Ordinal variables. So, Nominal variables are those variables that come in the format of perfect categories or mutually exclusive categories.

**Is the interval and ratio scale the same in SPSS?**

In SPSS, for all practical purposes, it combines the Interval and Ratio scale into one and called Scale variable. We can see the meter scale kind of symbol for the scale variable, so it is showing that it’s a quantitative variable.

### Can a variable be ranked or quantified in SPSS?

While some can be ranked as well as can be quantified. Upon importing the data for any variable into the SPSS input file, it takes it as a scale variable by default since the data essentially contains numeric values. It is important to change it to either nominal or ordinal or keep it as scale depending on the variable the data represents.
