Quick Answer: What Is Considered Discrete Data?

What type of data is discrete?

Discrete data is a count that can’t be made more precise.

Typically it involves integers.

For instance, the number of children (or adults, or pets) in your family is discrete data, because you are counting whole, indivisible entities: you can’t have 2.5 kids, or 1.3 pets..

How do you know if data is discrete or continuous?

Discrete data involves round, concrete numbers that are determined by counting. Continuous data involves complex numbers that are measured across a specific time interval.

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

Is time in minutes discrete or continuous data?

Time is a continuous variable, it can take any positive value in an interval. Even when we measure it in minutes, it can be measured with infinite precision, for example: 0.125 minutes or 0.13333 minutes.

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 discrete numbers example?

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 weight discrete or continuous?

Continuous random variables have numeric values that can be any number in an interval. For example, the (exact) weight of a person is a continuous random variable. Foot length is also a continuous random variable. Continuous random variables are often measurements, such as weight or length.

What is the similarities of discrete and continuous?

Key Difference Between Discrete And Continuous Variables 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.

Can time be 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. … The number of measurements between any two time periods is finite.

What is meant by discrete data?

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.

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.

What is the difference between discrete and continuous probability distribution?

A discrete distribution means that X can assume one of a countable (usually finite) number of values, while a continuous distribution means that X can assume one of an infinite (uncountable) number of different values.

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.

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.

Is discrete data a whole number?

Attribute data (aka discrete data) is data that can’t be broken down into a smaller unit and add additional meaning. It is typically things counted in whole numbers.

Is height a discrete variable?

The word discrete means countable. For example, the number of students in a class is countable, or discrete. In general, quantities such as pressure, height, mass, weight, density, volume, temperature, and distance are examples of continuous random variables. …

How do you convert discrete data to continuous data?

We often convert continuous variables into discrete ones. We do this by dividing up the continuous variable into ranges of values. We then assign the same discrete value to all values of the continuous variable that fall within a certain range.
