Question: Is Age Continuous Or Categorical?

Is age a categorical data?

Categorical variables represent types of data which may be divided into groups.

Examples of categorical variables are race, sex, age group, and educational level..

How do you represent categorical data?

Presenting categorical data: key termsBar chart – A chart or graph that represents grouped data with rectangles whose lengths are relative to the values they represent.Contingency table – A table that displays the relationship between one categorical variable and another.Crosstab – See ‘Contingency table’More items…

How do you know if something is discrete or continuous?

Definition: A set of data is said to be continuous if the values belonging to the set can take on ANY value within a finite or infinite interval. Definition: A set of data is said to be discrete if the values belonging to the set are distinct and separate (unconnected values).

What type of variable is age in years?

Mondal[1] suggests that age can be viewed as a discrete variable because it is commonly expressed as an integer in units of years with no decimal to indicate days and presumably, hours, minutes, and seconds.

Is age an interval or ratio?

[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.

Can you find the mean of categorical data?

There is no way of finding a mean from this data because there isn’t an “average” eye color. You can find the proportions, but not the mean.

What does categorical data mean?

more … Data that can be divided into specific groups, such as favorite color, age group, type of food, sport, etc.

What is an example of a continuous variable?

Continuous variables are numeric variables that have an infinite number of values between any two values. A continuous variable can be numeric or date/time. For example, the length of a part or the date and time a payment is received.

How do you know if a variable is discrete or continuous?

A discrete variable is a variable whose value is obtained by counting. A continuous variable is a variable whose value is obtained by measuring. A random variable is a variable whose value is a numerical outcome of a random phenomenon. A discrete random variable X has a countable number of possible values.

Is age a continuous or categorical variable?

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.

Are years a continuous variable?

Time is a continuous variable. You could turn age into a discrete variable and then you could count it. For example: A person’s age in years.
