Question: How Do You Know If A Variable Is Discrete Or Continuous?

Which of the following is an example of continuous variable?

Answer: The weight of a fire fighter would be an example of a continuous variable; since a fire fighter’s weight could take on any value between 150 and 250 pounds.

Suppose we flip a coin and count the number of heads.

The number of heads could be any integer value between 0 and plus infinity..

What is an example of continuous quantitative variable?

Examples of continuous variables are body mass, height, blood pressure and cholesterol. A discrete quantitative variable is one that can only take specific numeric values (rather than any value in an interval), but those numeric values have a clear quantitative interpretation.

How do you know if a variable is continuous?

If you start counting now and never, ever, ever finish (i.e. the numbers go on and on until infinity), you have what’s called a continuous variable. If your variable is “Number of Planets around a star,” then you can count all of the numbers out (there can’t be an infinite number of planets).

What is the difference between discrete and continuous?

Discrete data is information that can only take certain values. … Continuous data is data that can take any value. Height, weight, temperature and length are all examples of continuous data.

What is variable difference between 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).

What are two examples of continuous variables?

In general, quantities such as pressure, height, mass, weight, density, volume, temperature, and distance are examples of continuous random variables.

Can gender be a continuous 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 similarities of discrete and continuous variable?

The simplest similarity that a discrete variable shares with a continuous variable is that both are variables meaning they have a changing value. Besides that, they are also statistical terminologies used for comparative analysis.

What are the two types of discrete variables?

Discretely measured responses can be:Nominal (unordered) variables, e.g., gender, ethnic background, religious or political affiliation.Ordinal (ordered) variables, e.g., grade levels, income levels, school grades.Discrete interval variables with only a few values, e.g., number of times married.More items…

What makes a variable continuous?

A continuous variable is one which can take on an uncountable set of values. For example, a variable over a non-empty range of the real numbers is continuous, if it can take on any value in that range. The reason is that any range of real numbers between and with. is infinite and uncountable.

Is salary a discrete or continuous 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 hours of sleep discrete or continuous?

Amount of sleep is a variable. 3, 5, 9 hours of sleep are different values for that variable. Variables can be continuous or discrete. Question: Are these variables discrete or continuous?…Frequency distribution table:Score (X)Frequency (f)(Hours)(Number of people with this score)3142561 more row

How do you tell if a graph is discrete or continuous?

When figuring out if a graph is continuous or discrete we see if all the points are connected. If the line is connected between the start and the end, we say the graph is continuous. If the points are not connected it is discrete.

Is age continuous or discrete?

We could be infinitly accurate and use an infinite number of decimal places, therefore making age continuous. However, in everyday appliances, all values under 6 years and above 5 years are called 5 years old. So we use age usually as a discrete variable.

What are the types of continuous variables?

There are two types of continuous variables namely interval and ratio variables.
