Is number of children continuous or categorical?

Is number of children continuous or categorical?

No, it’s not. It’s a discrete numerical variable. Numerical variables are quantitative. In opposition, a categorical variable would be called qualitative, even if there’s an intrinsic ordering to them (e.g. an ordered categorical variable).

Is the number of children in a family a discrete variable?

A discrete variable cannot take the value of a fraction between one value and the next closest value. Examples of discrete variables include the number of registered cars, number of business locations, and number of children in a family, all of of which measured as whole units (i.e. 1, 2, 3 cars).

Is family size a continuous variable?

Income is a continuous variable. Household size and number of computers are discrete variables.

Is number of students continuous variable?

The word discrete means countable. For example, the number of students in a class is countable, or discrete. Between any two values of a continuous random variable, there are an infinite number of other valid values.

Is children a continuous variable?

It is discrete as if it was continuous it would mean you can have 225 children, which isn’t possible. With discrete, it means you only have 0,1,2,3,etc. children.

What type of variable is number of people in a household?

Discrete variables
Discrete variables You can enumerate all possible values (0, 0.1, 0.2…) and see that the number of possible values is finite: it is 101! Another example of a discrete variable is the number of people in a household for a household of size 20 or less.

Is number of children a continuous?

Is the variable number of siblings discrete or continuous?

The number of siblings and student height represent numerical variables. Because the number of siblings is a count, it is discrete. Height varies continuously, so it is a continuous numerical variable.

Is number of siblings discrete or continuous?

Is age a continuous variable?

Explanation: Age is measured in units that, if precise enough, could be any number. Therefore the set they come from is infinite. We could be infinitly accurate and use an infinite number of decimal places, therefore making age continuous.

What variables are continuous?

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.

Is number of dependents continuous or discrete?

It is discrete as if it was continuous it would mean you can have 225 children, which isn’t possible.

Which is an example of a continuous variable?

Some examples of variables in statistics might include age, eye color, height, number of siblings, gender, or number of pets. Our definition of a continuous variable also mentions that it’s quantitative. Quantitative data involves quantities or numbers. In the examples of variables listed earlier, your age,…

Is the age a continuous variable or a discrete variable?

However, we may work with only the number of weeks since birth and thus transforming the age into a discrete variable. The variable age remains a quantitative continuous variable but the variable we are working on (i.e., the number of weeks since birth) is a quantitative discrete variable.

Is it possible to calculate the mean of a continuous variable?

For instance, it is impossible to compute the mean of the variable “hair color” as you cannot sum brown and blond hair. On the other hand, finding the mode of a continuous variable does not really make any sense because most of the time there will not be two exact same values, so there will be no mode.

Is the variable age a quantitative or qualitative variable?

The variable age remains a quantitative continuous variable but the variable we are working on (i.e., the number of weeks since birth) is a quantitative discrete variable. From quantitative to qualitative Let’s say we are interested in the Body Mass Index (BMI).
