Is age categorical or continuous?
Is the age categorical or continuous?
Age is technically continuous and proportional. After all, a person’s age has a significant zero point (birth) and is continuous if measured accurately enough. It is significant to say that someone (or something) is 7.28 years old.
Is age a categorical variable?
Categorical variables represent data types that can be divided into groups. Examples of categorical variables are race, gender, age group, and education level.
Is age a continuous variable?
A variable is called continuous if it can take on infinitely many real values. Examples of continuous variables are distance, age, and temperature. Measuring a continuous variable is limited by the methods used or by the accuracy of the measuring equipment.
Is the categorical age nominal or ordinal?
Age can be both nominal and ordinal, depending on the question type. For example, how old are you to collect nominal data, while are you the firstborn or what is your position in your family to collect ordinal data. Age becomes an ordinal datum when there is some sort of order.
Is age categorical or qualitative?
In our medical example, age is an example of a quantitative variable because it can take on multiple numeric values. It also makes sense to think of it in numbers, i.e. a person can be 18 or 80 years old. Weight and height are also examples of quantitative variables.
How do you identify categorical variables?
A Test for Identifying Categorical Data
- Calculate the number of unique values in the dataset.
- Calculate the difference between the number of unique values in the dataset and the total number of values in the dataset.
- Calculate the percentage difference of the total number of values in the dataset.
What are the two types of categorical data?

Is sex a continuous variable?
Gender can be a continuous variable, not just a categorical one: Commentary on Hyde, Bigler, Joel, Tate, and van Anders (2019)
Why is age data continuous?
Age is measured in units which, if accurate enough, can be any number. Hence the set from which they come is infinite. … We could be infinitely precise and use infinitely many decimal places, thus making the age continuous.
What variable is age?
There are basically 2 types of variables in statistics: Numerical variables: Numbers that should be treated as they are commonly used in mathematics. For example, age and weight would be considered numeric variables, while phone number and zip code would not be considered numeric variables.
What kind of variable is gender?
There are two types of categorical variables, nominal and ordinal. A nominal variable has no intrinsic order to its categories. For example, gender is a categorical variable with two categories (male and female) with no intrinsic ordering of the categories. An ordinal variable has a unique order.
