## Is gender an interval or ratio?

There are four basic levels: nominal, ordinal, interval, and ratio.

A variable measured on a “nominal” scale is a variable that does not really have any evaluative distinction.

One value is really not any greater than another.

A good example of a nominal variable is sex (or gender)..

## Is race nominal or ordinal?

Typical examples of nominal variables are gender, race, color, city, etc.

## Is time an interval?

A longer length of time can be divided into a number of shorter periods of time, all of the same length. These are called time intervals. For example, say you wanted to measure the speed of a car over a journey taking an hour. You could divide the hour up into time intervals of ten minutes.

## Is year of birth interval or ratio data?

Unlike nominal- and ordinal-level data, which are qualitative in nature, interval- and ratio-level data are quantitative. Examples of interval level data include temperature and year. Examples of ratio level data include distance and area (e.g., acreage).

## Is heart rate an interval or ratio?

Suppose a person’s heart rate is measured. This measurement is a ratio scale measurement because a score of 0 beats per minute (bmp) represents a stopped heart and a heart rate of, say, 100 bpm is twice as fast as a heart rate of 50 bpm.

## Is time an interval or ratio?

Ratio data is interval data with a natural zero point. For example, time is ratio since 0 time is meaningful. Degrees Kelvin has a 0 point (absolute 0) and the steps in both these scales have the same degree of magnitude.

## Is blood sugar an interval or ratio?

A numerical or continuous variable (attribute) is one that may take on any value within a finite or infinite interval (e.g., height, weight, temperature, blood glucose, …). There are two types of numerical variables, interval and ratio.

## Why is the ratio scale most powerful?

Among four levels of measurement, including nominal, ordinal, interval, and ratio scales, the ratio scale is the most precise. Because attributes in a ratio scale have equal distances and a true zero point, statements about the ratio of attributes can be made.

## Is weight an interval or ratio?

When working with ratio variables, but not interval variables, the ratio of two measurements has a meaningful interpretation. For example, because weight is a ratio variable, a weight of 4 grams is twice as heavy as a weight of 2 grams.

## Is percentage an interval or ratio?

The percentage of votes received by a candidate, Gross Domestic Product per Capita, and the crime rate are all ratio variables. Dichotomous variables (those with only two values) are a special case, and may sometimes be treated as nominal, ordinal, or interval.

## Is income nominal or ordinal?

For example, income is a variable that can be recorded on an ordinal or a ratio scale: At an ordinal level, you could create 5 income groupings and code the incomes that fall within them from 1–5. At a ratio level, you would record exact numbers for income.

## What are the 5 types of measurements?

Types of data measurement scales: nominal, ordinal, interval, and ratio.
