Is Height A Discrete Variable?

Is color a discrete or continuous variable?

A continuous variable is one which can take on a value between any other two values, such as: indoor temperature, time spent waiting, water consumed, color wavelength, and direction of travel.

A discrete variable corresponds to a digital quantity, while a continuous variable corresponds to an analog quantity..

Is shoe size a discrete variable?

Shoe size is whole number (discrete), but the underlying measure is foot length which is measurement (continuous) data. Even half sizes are still not really measurement but “whole number”, because there is nothing between size 8 and 8 1/2.

Can age be a discrete 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 birth year continuous or discrete?

What are the examples of discrete random variable?

Every probability pi is a number between 0 and 1, and the sum of all the probabilities is equal to 1. Examples of discrete random variables include: The number of eggs that a hen lays in a given day (it can’t be 2.3) The number of people going to a given soccer match.

Which is a discrete variable?

A variable is a quantity whose value changes. A discrete variable is a variable whose value is obtained by counting. A discrete random variable X has a countable number of possible values. … Example: Let X represent the sum of two dice.

How do you know if it 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).

Is money a discrete or continuous variable?

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.

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.

Is height a discrete or continuous variable?

Examples of a continuous variable are distance, age and temperature. The measurement of a continuous variable is restricted by the methods used, or by the accuracy of the measuring instruments. For example, the height of a student is a continuous variable because a student may be 1.6321748755… metres tall.
