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.
What is discrete data example?
Discrete data is information that can only take certain values . These values don’t have to be whole numbers (a child might have a shoe size of 3.5 or a company may make a profit of £3456.25 for example) but they are fixed values – a child cannot have a shoe size of 3.72!
What are discrete numbers?
Discrete data can only take particular values . There may potentially be an infinite number of those values, but each is distinct and there’s no grey area in between. Discrete data can be numeric — like numbers of apples — but it can also be categorical — like red or blue, or male or female, or good or bad.
What are examples of discrete?
| Discrete data Continuous data | Some common examples of discrete data are the number of students, the number of children, the shoe size, and so on Some common examples of continuous data are height, weight, length, time, temperature, age, and so on |

What is discrete series example?
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 gender a discrete variable?
| 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 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 .
Is hours of sleep discrete or continuous?

What is an example of quantitative discrete data?
A quantitative variable can be either continuous or discrete. ... Examples of discrete quantitative variables are number of needle punctures, number of pregnancies and number of hospitalizations . For these examples, positive whole numbers are the only possible values (i.e., it is not possible to have 1.5 pregnancies).
What is discrete behavior?
DISCRETE BEHAVIOR : A behavior that has a clearly discriminable beginning and end . Lever presses, sneezes, and writing answers to addition problems are examples of discrete responses.
What is an example of a discrete random variable?
If a random variable can take only a finite number of distinct values, then it must be discrete. Examples of discrete random variables include the number of children in a family, the Friday night attendance at a cinema, the number of patients in a doctor’s surgery, the number of defective light bulbs in a box of ten .
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.
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.
What you mean by discrete series?
The Discrete series can be defined as:
A system wherein the frequencies of a particular variable are shown , but all the variables are without any class intervals. ... Each and every frequency is systematically multiplied with the variable.
