Categorical variables represent types of data which may be divided into groups. Examples of categorical variables are race, sex, age group, and educational level.
What kind of variable is age?
continuous
A variable is said to be continuous if it can assume an infinite number of real values. Examples of a continuous variable are distance, age and temperature.
Is age quantitative nominal or ordinal?
Age is frequently collected as ratio data, but can also be collected as ordinal data. This happens on surveys when they ask, “What age group do you fall in?” There, you wouldn’t have data on your respondent’s individual ages – you’d only know how many were between 18-24, 25-34, etc.
Is age quantitative discrete or continuous?
Age is measured in units that, if precise enough, could be any number. Therefore the set they come from is infinite. For example, someone could be 22.32698457 years old or 22.32698459 years old. We could be infinitly accurate and use an infinite number of decimal places, therefore making age continuous.
Is age quantitative or qualitative data?
Examples of quantitative characteristics are age, BMI, creatinine, and time from birth to death. Examples of qualitative characteristics are gender, race, genotype and vital status. Qualitative variables are also called categorical variables.
What level of measure is age?
[Ratio] Age is at the ratio level of measurement because it has an absolute zero value and the difference between values is meaningful. For example, a person who is 20 years old has lived (since birth) half as long as a person who is 40 years old.
Is gender ordinal or nominal?
A nominal variable has no intrinsic ordering to its categories. For example, gender is a categorical variable having two categories (male and female) with no intrinsic ordering to the categories. An ordinal variable has a clear ordering.
Is height nominal or ordinal?
– Quora. “A person’s height” is ratio data. Nominal data has values that have no numerical meaning, such as a person’s gender (M, F) or possible colors of a new Chevy Cruz this year.

Which is the type of variable is age?
Variables aren’t always ‘quantitative’ or numerical. In this way, is age a categorical variable? Categorical variables take category or label values and place an individual into one of several groups. Quantitative variables take numerical values and represent some kind of measurement.
Are there any problems based on age for Quantitative Aptitude?
The problems based on age asked in the quantitative aptitude section are kind of brain teasers which when read at first may seem to be complex, but when solved step by step is easy to answer.
When do you use age as a discrete variable?
For example, someone could be 22.32698457 years old or 22.32698459 years old. We could be infinitly accurate and use an infinite number of decimal places, therefore making age continuous. However, in everyday appliances, all values under 6 years and above 5 years are called 5 years old. So we use age usually as a discrete variable.
