We could be infinitely precise and use infinitely many decimals, making the age continuous. For everyday devices, however, all values less than 6 years and greater than 5 years are referred to as 5 years. We therefore use age generally as a discrete variable.
Can age be a discrete variable?
Mondal[1] proposes that age can be considered a discrete variable since it is usually expressed as an integer in units of years with no decimal places to denote days and presumably hours, minutes and seconds.
Is age in years a discrete or continuous variable?
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 discrete quantitative variable?
From continuous to discrete The age variable remains a continuous quantitative variable, but the variable we are working on (ie number of weeks since birth) is a discrete quantitative variable.
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.
Is gender a discrete or continuous variable?
Variable reference table: some examples
< tr>
< td> phone number < /td>| variable | variable type | variable scaling |
|---|---|---|
| gender | discrete | categorical |
| gender as binary encoding 1/0 | discrete | categorical |
| true/false | discrete | categorical |
| Discrete | Nominal |
Is money discrete or continuous?
A continuous distribution must have an infinite number of values between $0.00 and $0.01. Money does not have this quality; there is always an indivisible unit of smaller money. And as such, money is a discrete entity.
Is gender a discrete variable?
Discrete data: when the variable is limited to specific setpoints. For example, male or female are categorical discrete data values.
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.
