Can a discrete variable take fractional value?

Can a discrete variable take fractional value?

Discrete data can take only certain values. Only a finite number of values is possible, and the values cannot be subdivided into fractions.

Can a discrete variable take on any value?

, the set of natural numbers. In other words; a discrete variable over a particular range of real values is one for which, for any value in the range that the variable is permitted to take on, there is a positive minimum distance to the nearest other permissible value.

What values can a discrete random variable take on?

A discrete random variable is one which may take on only a countable number of distinct values such as 0,1,2,3,4,…….. Discrete random variables are usually (but not necessarily) counts. If a random variable can take only a finite number of distinct values, then it must be discrete.

Are discrete variables always whole numbers?

Discrete random variables are considered countable values, since you could count a whole number of them.

What type of variable Cannot take a value of fraction?

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).

Can a discrete variable have decimals?

Discrete data CANNOT have decimals. Quantitative data can be divided into two portions: discrete and continuous data.

Can a discrete variable be a float?

Values of discrete variables are stored as floats; the numbers corresponds to indices in the list of values. True if the variable’s values are stored as floats.

Can a discrete variable be negative?

Your intuition is correct — a discrete variable can take on negative values. The example is just an example: a person can’t have −2 children, but the difference in scores between Home and Away sports teams can be −2 when the Home team is behind by two points.

Can a discrete variable take any value?

Yes, a discrete variable can take any value , integer, fraction, mixed number , rational decimal , or rational. It’s just that a discrete variable cannot have a range of allowable values that are part of a continuous range for that variable. Shoe sizes can be used for discrete variable , four, 4 1/2, five, 5 1/2, six, etc.

What is discrete random variable give an example?

Example (Discrete Random Variable) Flipping a coin twice, the random variable Number of Heads 2f0;1;2gis a discrete random variable. Number of aws found on a randomly chosen part 2f0;1;2;:::g.

What is the difference between a continuous and discrete variable?

A continuous variable can take any value (possibly within a limited range), a discrete variable can only take on a fixed number of values. But it’s not really a crystal-clear dichotomy.

Is weight a discrete or continuous random variable?

Because the possible values are discrete and countable, this random variable is discrete, but it might be a more convenient, simple approximation to assume that the measurements are values on a continuous random variable as ‘weight’ is theoretically continuous. 4/23 Continuous Random Variables De\\fnition (Continuous Random Variable)
