Quick Answer: Is Age In Years Discrete Or Continuous?

What type of variable is age in years?

An Example: Age A great example of this is a variable like age.

Age is, technically, continuous and ratio.

A person’s age does, after all, have a meaningful zero point (birth) and is continuous if you measure it precisely enough.

It is meaningful to say that someone (or something) is 7.28 year old..

Is age group a discrete variable?

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.

What kind of variable is gender?

nominal variableA nominal variable (as in “noun”) cannot be counted. For example, gender is a nominal variable having two categories (male and female) and there is no intrinsic ordering to the categories. You can assign a numerical value (e.g “Male” = 1, “Female” = 2) but you cannot rank the data from highest to lowest.

Is gender a discrete variable?

Discrete data: when the variable is restricted to specific defined values. For example, “male” or “female” are categorical discrete data values.

How do you know if something 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 height a discrete variable?

The word discrete means countable. For example, the number of students in a class is countable, or discrete. In general, quantities such as pressure, height, mass, weight, density, volume, temperature, and distance are examples of continuous random variables. …

Is annual income continuous or discrete?

An annual income of a person is a discrete variable. This implies it cannot be constant, but if it is more convenient for your program, you can consider it as a continuous attribute, because there are so many meanings for it, again. The profits will often be broken up into groups of polls and other data sets.

Is age a discrete quantitative variable?

From continuous to discrete 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 age an interval or ratio?

A ratio scale has the first characteristic of the interval scale (interval) but also has a meaningful zero point—which means the absence of the attribute. This enables multiplication and division on the values. Using the aforementioned definition, age is in a ratio scale.

What data type is age?

Age can be both nominal and ordinal data depending on the question types. I.e “How old are you” is a used to collect nominal data while “Are you the first born or What position are you in your family” is used to collect ordinal data. Age becomes ordinal data when there’s some sort of order to it.

How do you know if data is discrete or continuous?

Discrete data involves round, concrete numbers that are determined by counting. Continuous data involves complex numbers that are measured across a specific time interval.

Is Money discrete or continuous?

A continuous distribution should have an infinite number of values between $0.00 and $0.01. Money does not have this property – there is always an indivisible unit of smallest currency. And as such, money is a discrete quantity.
