 # Quick Answer: What Is Discrete In Statistics?

## What is the difference between discrete and continuous in statistics?

A discrete variable is a variable whose value is obtained by counting.

A continuous variable is a variable whose value is obtained by measuring.

A discrete random variable X has a countable number of possible values.

Example: Let X represent the sum of two dice..

## What are 3 types of variables?

A variable is any factor, trait, or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables: independent, dependent, and controlled.

## Is gender a discrete or continuous variable?

## 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 discrete data example?

Discrete data is information that we collect that can be counted and that only has a certain number of values. Examples of discrete data include the number of people in a class, test questions answered correctly, and home runs hit.

## 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 are two examples of continuous variables?

You often measure a continuous variable on a scale. For example, when you measure height, weight, and temperature, you have continuous data. With continuous variables, you can calculate and assess the mean, median, standard deviation, or variance.

## 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

## 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 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.

## Which is an example of a discrete distribution?

Common examples of discrete distribution include the binomial, Poisson, and Bernoulli distributions. These distributions often involve statistical analyses of “counts” or “how many times” an event occurs. In finance, discrete distributions are used in options pricing and forecasting market shocks or recessions.

## What is the formula of discrete series?

Summary: The mean of discrete series is obtained by simply adding up all the observations and then dividing the sum by the total number of observations.

## What is the value of N in case of discrete series?

Answer: N = Number of observations. f1,f2,f3,…,fn = Different values of frequency f.

## How do you write a discrete series?

If we are to prepare discrete series from individual series or raw data, it is better to place values in ascending order, then against these variables we put tally bar for each item against the corresponding variable, then number of total tally bars is counted and a numerical number is put in 3rd column as frequency.

## Is number of students discrete or continuous?

Discrete and Continuous Random Variables. The word discrete means countable. For example, the number of students in a class is countable, or discrete.

## What is a continuous variable in statistics?

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 the similarities and differences between continuous and discrete variable?

Discrete variables are the variables, wherein the values can be obtained by counting. On the other hand, Continuous variables are the random variables that measure something. Discrete variable assumes independent values whereas continuous variable assumes any value in a given range or continuum.
