What is a discrete domain?

What is a discrete domain?

A discrete domain is a set of input values that consists of only certain numbers in an interval. EXAMPLE: Integers from 1 to 5. −2 −1.

What is discrete domain and range?

A discrete domain is a set of input values that consist of only certain numbers in an interval. State the domain and range associated with the graph below. State whether this relation is a function. A continuous domain is a set of input values that consists of all numbers in an interval.

How do you tell if a situation 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).

What is discrete example?

Examples of discrete data The number of customers who bought different items. The number of computers in each department. The number of items you buy at the grocery store each week.

Can a discrete function be continuous?

This means that the values of the functions are not connected with each other. For example, a discrete function can equal 1 or 2 but not 1.5. For example, if at one point, a continuous function is 1 and 2 at another point, then this continuous function will definitely be 1.5 at yet another point.

Is blood pressure discrete or continuous?

Is blood pressure an example of continuous or discrete data? Blood pressure is an example of continuous data. Blood pressure can be measured to as many decimals as the measuring instrument allows.

Is wage a discrete variable?

In terms of statistics, this describes variables that assume only particular, distinct values and that are not continuous. For example, salary levels and performance classifications are discrete variables, whereas height and weight are continuous variables.

Is gender a discrete variable?

On purpose, I made it sound distinct that a variable is either discrete or continuous….Variable Reference Table : Few Examples.

Variable	Variable Type	Variable Scale
Gender	Discrete	Categorical
Gender as Binary 1/0 Coding	Discrete	Categorical
True/False	Discrete	Categorical
Phone Number	Discrete	Nominal

Is time a discrete or continuous variable?

Time is a continuous variable. You could turn age into a discrete variable and then you could count it. For example: A person’s age in years.

Is someone’s age discrete or continuous?

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 of a person 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 is the difference between a discrete and continuous variable?

Discrete and continuous variables are two types of quantitative variables: Discrete variables represent counts (e.g. the number of objects in a collection). Continuous variables represent measurable amounts (e.g. water volume or weight).

Is a Social Security number discrete or continuous?

Some variables, such as social security numbers and zip codes, take numerical values, but are not quantitative: They are qualitative or categorical variables.

Is ZIP code discrete or continuous?

continuous Discrete Attribute Has only a finite or countably infinite set of values Examples from text: zip codes, counts, or the set of words in a collection of documents, binary data.

Is IQ a discrete or continuous variable?

IQ – discrete. IQ scores are always integers – 100, 110, 180, etc.

Is eye color discrete or continuous?

Examples. The following are examples of discrete variables: Gender. Eye color (brown, blue, green, hazel)

Is hair Colour discrete or continuous?

For example, number of books is a discrete random variable. On the other hand, hair color is not a random variable because hair color is not numeric. Also, any decimal between 0 and 1 is not discrete because we cannot list out all the decimals.

What variable is eye Colour?

Certainly, eye color is a nominal variable, since it is multi-valued (blue, green, brown, grey, pink, black), and there is no clear scale on which to fit the different values.

Is skin tone continuous variation?

Some of these differences vary over a whole range, for example the height, skin colour and weight of people. We call this type continuous variation.

Which skin tone is most attractive?

A new study by Missouri School of Journalism researcher Cynthia Frisby found that people perceive a light brown skin tone to be more physically attractive than a pale or dark skin tone.

What is an example of continuous variation?

Human height is an example of continuous variation. It ranges from that of the shortest person in the world to that of the tallest person. Any height is possible between these values. So it is continuous variation.
