Which of the following is an example of a variable measured at the ordinal level of measurement?

In ordinal measurement, the values stress the order or rank of the values, but the differences between each one is not really known. You might consider yourself middle class, but how much better off are you compared to a friend of yours who identified him/herself as lower class? In ordinal variables, the numerical values name the attribute or characteristics but also allow us to place the categories in a natural and reasonable order.

Other Examples of Ordinal Variable:

Likert scale – Strongly disagree; Disagree; Neither agree nor disagree; Agree; Strongly agree.
Class standing – Freshman, sophomore, junior, senior
Socioeconomic standing – Lower, middle, and upper class
Quality of democracy – Very high, high, medium, low, very low

Why do we need to learn this? Because many social science and political science variables tend to be nominal (think of NAME) or ordinal (think of ORDER), it is important that you are able to understand and distinguish them clearly.

What might be confusing about Ordinal variable?

Another common occurrence in the social sciences is the creation of categories from an underlying measurement. For example, the performance of a government policy may be assessed as superior, effective, minimal, or inadequate. These four categories correspond to an objective score as follows: Superior – 90 to 100; Effective – 70 to 89; Minimal – 40 to 69; Inadequate – 0 to 39. Even though the four categories were determined by a score from 1 to 100, the categories themselves are measured at the ordinal level.

Can you try it on your own?

True or False: You are hired by a marketing research agency to test a new iPhone. Consumers were asked to rate it outstanding, very good, fair or poor. The level of measurement for this market research is ordinal.
A: True
B: False
True or False: You are trying to study the impact of socio-economic status of college students and their interests in politics. You ask your respondents to rate their socio-economic status as follows; low, middle, or upper class. The level of measurement for the socio-economic variable is ordinal.
A: True

B: False

In statistics, we use data to answer interesting questions. But not all data is created equal. There are actually four different data measurement scales that are used to categorize different types of data:

1. Nominal

2. Ordinal

3. Interval

4. Ratio

In this post, we define each measurement scale and provide examples of variables that can be used with each scale.

The simplest measurement scale we can use to label variables is a nominal scale.

Nominal scale: A scale used to label variables that have no quantitative values.

Some examples of variables that can be measured on a nominal scale include:

Gender: Male, female
Eye color: Blue, green, brown
Hair color: Blonde, black, brown, grey, other
Blood type: O-, O+, A-, A+, B-, B+, AB-, AB+
Political Preference: Republican, Democrat, Independent
Place you live: City, suburbs, rural

Variables that can be measured on a nominal scale have the following properties:

They have no natural order. For example, we can’t arrange eye colors in order of worst to best or lowest to highest.
Categories are mutually exclusive. For example, an individual can’t have both blue and brown eyes. Similarly, an individual can’t live both in the city and in a rural area.
The only number we can calculate for these variables are counts. For example, we can count how many individuals have blonde hair, how many have black hair, how many have brown hair, etc.
The only measure of central tendency we can calculate for these variables is the mode. The mode tells us which category had the most counts. For example, we could find which eye color occurred most frequently.

The most common way that nominal scale data is collected is through a survey. For example, a researcher might survey 100 people and ask each of them what type of place they live in.

Question: What type of area do you live in?

Possible Answers: City, Suburbs, Rural.

Using this data, the researcher can find out how many people live in each area, as well as which area is the most common to live in.

Ordinal

The next type of measurement scale that we can use to label variables is an ordinal scale.

Ordinal scale: A scale used to label variables that have a natural order, but no quantifiable difference between values.

Some examples of variables that can be measured on an ordinal scale include:

Satisfaction: Very unsatisfied, unsatisfied, neutral, satisfied, very satisfied
Socioeconomic status: Low income, medium income, high income
Workplace status: Entry Analyst, Analyst I, Analyst II, Lead Analyst
Degree of pain: Small amount of pain, medium amount of pain, high amount of pain

Variables that can be measured on an ordinal scale have the following properties:

They have a natural order. For example, “very satisfied” is better than “satisfied,” which is better than “neutral,” etc.
The difference between values can’t be evaluated. For example, we can’t exactly say that the difference between “very satisfied and “satisfied” is the same as the difference between “satisfied” and “neutral.”
The two measures of central tendency we can calculate for these variables are the mode and the median. The mode tells us which category had the most counts and the median tells us the “middle” value.

Ordinal scale data is often collected by companies through surveys who are looking for feedback about their product or service. For example, a grocery store might survey 100 recent customers and ask them about their overall experience.

Question: How satisfied were you with your most recent visit to our store?

Possible Answers: Very unsatisfied, unsatisfied, neutral, satisfied, very satisfied.

Using this data, the grocery store can analyze the total number of responses for each category, identify which response was most common, and identify the median response.

Interval

The next type of measurement scale that we can use to label variables is an interval scale.

Interval scale: A scale used to label variables that have a natural order and a quantifiable difference between values, but no “true zero” value.

Some examples of variables that can be measured on an interval scale include:

Temperature: Measured in Fahrenheit or Celsius
Credit Scores: Measured from 300 to 850
SAT Scores: Measured from 400 to 1,600

Variables that can be measured on an interval scale have the following properties:

These variables have a natural order.
We can measure the mean, median, mode, and standard deviation of these variables.
These variables have an exact difference between values. Recall that ordinal variables have no exact difference between variables – we don’t know if the difference between “very satisfied” and “satisfied” is the same as the difference between “satisfied” and “neutral.” For variables on an interval scale, though, we know that the difference between a credit score of 850 and 800 is the exact same as the difference between 800 and 750.
These variables have no “true zero” value. For example, it’s impossible to have a credit score of zero. It’s also impossible to have an SAT score of zero. And for temperatures, it’s possible to have negative values (e.g. -10° F) which means there isn’t a true zero value that values can’t go below.

The nice thing about interval scale data is that it can be analyzed in more ways than nominal or ordinal data. For example, researchers could gather data on the credit scores of residents in a certain county and calculate the following metrics:

Median credit score (the “middle” credit score value)
Mean credit score (the average credit score)
Mode credit score (the credit score that occurs most often)
Standard deviation of credit scores (a way to measure how spread out credit scores are)

Ratio

The last type of measurement scale that we can use to label variables is a ratio scale.

Ratio scale: A scale used to label variables that have a natural order, a quantifiable difference between values, and a “true zero” value.

Some examples of variables that can be measured on a ratio scale include:

Height: Can be measured in centimeters, inches, feet, etc. and cannot have a value below zero.
Weight: Can be measured in kilograms, pounds, etc. and cannot have a value below zero.
Length: Can be measured in centimeters, inches, feet, etc. and cannot have a value below zero.

Variables that can be measured on a ratio scale have the following properties:

These variables have a natural order.
We can calculate the mean, median, mode, standard deviation, and a variety of other descriptive statistics for these variables.
These variables have an exact difference between values.
These variables have a “true zero” value. For example, length, weight, and height all have a minimum value (zero) that can’t be exceeded. It’s not possible for ratio variables to take on negative values. For this reason, the ratio between values can be calculated. For example, someone who weighs 200 lbs. can be said to weigh two times as much as someone who weights 100 lbs. Likewise someone who is 6 feet tall is 1.5 times taller than someone who is 4 feet tall.

Data that can be measured on a ratio scale can be analyzed in a variety of ways. For example, researchers could gather data about the height of individuals in a certain school and calculate the following metrics:

Median height
Mean height
Mode height
Standard deviation of heights
Ratio of tallest height to smallest height

Summary

The following table provides a summary of the variables in each measurement scale:

Property	Nominal	Ordinal	Interval	Ratio

Mode can be calculated	YES	YES	YES	YES
Median can be calculated		YES	YES	YES
Mean can be calculated			YES	YES

Which of the following is an example of an ordinal measurement?

Examples of ordinal variables include: socio economic status (“low income”,”middle income”,”high income”), education level (“high school”,”BS”,”MS”,”PhD”), income level (“less than 50K”, “50K-100K”, “over 100K”), satisfaction rating (“extremely dislike”, “dislike”, “neutral”, “like”, “extremely like”).

Which variable would be considered to be measured at the ordinal level?

Values of ordinal variables have a meaningful order to them. For example, education level (with possible values of high school, undergraduate degree, and graduate degree) would be an ordinal variable.

Which is an example of an ordinal measurement quizlet?

An example of ordinal measurement is the results of a horse race, which say only which horses arrived first, second, third, etc. but include no information about times.

What is an ordinal level of measurement quizlet?

Ordinal level. applies to data that may be arranged in order; differences between data values either cannot be determined or are meaningless. Interval level. applies to data that can be arranged in order; differences are meaningful.
