What is an example of discrete data?
Examples of discrete data include the number of people in a class, test questions answered correctly, and home runs hit.
Tables, or information displayed in columns and rows, and graphs, or structured diagrams that display the relationship among variables using two axes, are two ways to display discrete data..
Is Money discrete or continuous?
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.
Can data be both discrete and continuous?
Discrete data is information that can only take certain values. Height, weight, temperature and length are all examples of continuous data. …
What is an example of continuous random variable?
In general, quantities such as pressure, height, mass, weight, density, volume, temperature, and distance are examples of continuous random variables. … Between any two values of a continuous random variable, there are an infinite number of other valid values.
What is the meaning of continuous variable?
A continuous variable is a variable whose value is obtained by measuring, ie 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.
What is a discrete variable used for?
Discrete variables are countable in a finite amount of time. For example, you can count the change in your pocket. You can count the money in your bank account. You could also count the amount of money in everyone’s bank accounts.
What type of variable is gender?
categorical variableFor example, gender is a categorical variable having two categories (male and female) with no intrinsic ordering to the categories. An ordinal variable has a clear ordering. For example, temperature as a variable with three orderly categories (low, medium and high).
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 time a discrete variable?
Discrete time views values of variables as occurring at distinct, separate “points in time”, or equivalently as being unchanged throughout each non-zero region of time (“time period”)—that is, time is viewed as a discrete variable.
Is age continuous or discrete?
Age is measured in units that, if precise enough, could be any number. Therefore the set they come from is infinite. For example, someone could be 22.32698457 years old or 22.32698459 years old. We could be infinitly accurate and use an infinite number of decimal places, therefore making age continuous.
What is discrete in statistics?
A discrete distribution is one in which the data can only take on certain values, for example integers. A continuous distribution is one in which data can take on any value within a specified range (which may be infinite).
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).
What are the 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 is discrete series example?
ADVERTISEMENTS: Discrete series means where frequencies of a variable are given but the variable is without class intervals. Here the mean can be found by Three Methods. … Here each frequency is multiplied by the variable, taking the total and dividing total by total number of frequencies, we get X.
Is height a discrete variable?
A discrete variable is one that cannot take on all values within the limits of the variable. A variable such as a person’s height can take on any value. … Variables that can take on any value and therefore are not discrete are called continuous.
What are the example 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.

What are the similarities and differences between discrete and continuous random variables?
Alan P. A discrete random variable has a finite number of possible values. A continuous random variable could have any value (usually within a certain range). A discrete random variable is typically an integer although it may be a rational fraction.
What is a discrete variable in science?
A discrete variable is a kind of statistics variable that can only take on discrete specific values. The variable is not continuous, which means there are infinitely many values between the maximum and minimum that just cannot be attained, no matter what.
How do you know if data is discrete or continuous?
Discrete data is a numerical type of data that includes whole, concrete numbers with specific and fixed data values determined by counting. Continuous data includes complex numbers and varying data values that are measured over a specific time interval.
