## Is gender a random variable?

Terms in this set (15)

A random variable that can assume either a finite number of values or an infinite sequence of values such as 0,1,2,… … Experiment to sell an automobile, **Random Variable x = gender of the customer**. the possible values for random variable are 0 if male; 1 if female.

## Is gender is an example of a continuous random variable?

**Gender** can be a **continuous variable**, not just a categorical one: Comment on Hyde, Bigler, Joel, Tate, and van Anders (2019)

## What are the 3 types of random variable?

Types of Random variables. We classify random variables based on their probability distribution. A random variable either has an associated **probability distribution (Discrete Random Variable)**, or a probability density function (Continuous Random Variable).

## What is not a random variable?

A non-random variable is generally called a **Constant**. But constants are not really the opposite of random variables, in the same way integers are not the opposite of real numbers – they’re a subset.

## How do you find a random variable?

The formula is: **μ _{x} = x_{1}*p_{1} + x_{2}*p_{2} + hellip**; + x

_{2}*p

_{2}= Σ x

_{i}p

_{i}. In other words, multiply each given value by the probability of getting that value, then add everything up. For continuous random variables, there isn’t a simple formula to find the mean.

## What is one example of a continuous 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**.

## What is the difference between variable and random variable?

A variable is a symbol that represents some quantity. A variable is useful in mathematics because you can prove something without assuming the value of a variable and hence make a general statement over a range of values for that variable. A random variable is a value that follows some **probability distribution**.

## Is mean a random variable?

The mean can be regarded as a **measure of `central location’ of a random variable**. It is the weighted average of the values that X can take, with weights provided by the probability distribution. The mean is also sometimes called the expected value or expectation of X and denoted by E(X).

## Which of the following is an example of a discrete random variable?

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. The number of students that come to class on a given day.

## What is the range of a random variable?

The range of a random variable X, shown by Range(X) or RX, is **the set of possible values for X**. In the above example, Range(X)=RX={0,1,2,3,4,5}. The range of a random variable X, shown by Range(X) or RX, is the set of possible values of X.
