Why Is Continuous Data Better Than Discrete?

What are 2 examples of quantitative data?

Here are some example of quantitative data:A jug of milk holds one gallon.The painting is 14 inches wide and 12 inches long.The new baby weighs six pounds and five ounces.A bag of broccoli crowns weighs four pounds.A coffee mug holds 10 ounces.John is six feet tall.A tablet weighs 1.5 pounds.More items….

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.

What are 2 examples of qualitative data?

Examples of qualitative data include sex (male or female), name, state of origin, citizenship, etc. A more practical example is a case whereby a teacher gives the whole class an essay that was assessed by giving comments on spelling, grammar, and punctuation rather than score.

What is continuous quantitative data?

continuous data is quantitative data that can be measured. • it has an infinite number of possible values within. a selected range e.g. temperature range.

What is a quantitative continuous variable?

Quantitative variables can be classified as discrete or continuous. … Continuous variables are numeric variables that have an infinite number of values between any two values. A continuous variable can be numeric or date/time. For example, the length of a part or the date and time a payment is received.

Is income a continuous variable?

Income is a continuous variable.

Can you treat a categorical variable as continuous?

When you want to treat an ordinal variable as categorical, you can just include it in a CLASS statement or create a series of binary (“dummy”) variables for each of the categories. If you want to treat it as continuous, first be sure that the coding puts them in the correct monotonic order.

Is GPA a continuous variable?

Each value can be graphed as a separate point on a number line, with space between each point. … For example, the variable ” the number of children” is discrete and the variable ” GPA” is continuous. Since GPA can take an infinite number of possible values, for example interval 0.0 to 4.0.

Why is it generally best to collect data in its most continuous?

In practice, percentage data are often treated as continuous because thepercentage can take on any value along the continuum from zero to 100%. In addition, dividing a percentage point into two or more parts still makes sense. Discrete data are easy to collect and interpret.

What is difference between discrete and continuous data?

Discrete data is information that can only take certain values. … Continuous data is data that can take any value.

Is gender a discrete or continuous variable?

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

Can continuous data be converted to discrete 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.

Is percentage a discrete or continuous data?

In practice, percentage data are often treated as continuous because the percentage can take on any value along the continuum from zero to 100%. In addition, dividing a percentage point into two or more parts still makes sense. Discrete data are easy to collect and interpret.

Is discrete or continuous better?

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.

Why is continuous data important?

Continuous- Advantages Continuous data, unlike discrete has it’s advantages in how precise it’s data can be. It is very accurate and allows for a better understanding and to someone who knows numbers, can be a lot more useful to present more complicated data. It is also useful in using for graphs and surveys.

Is weight a discrete variable?

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. We view measurements as continuous even though the limitations of a ruler or a scale give discrete measurements.

Is continuous data qualitative or quantitative?

Quantitative Flavors: Continuous Data and Discrete Data There are two types of quantitative data, which is also referred to as numeric data: continuous and discrete. As a general rule, counts are discrete and measurements are continuous.

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.

What type of data is continuous?

Continuous data are numerical data that can theoretically be measured in infinitely small units. For example, blood pressure is usually measured to the nearest 2mm Hg, but could be measured with much greater resolution of difference. The interval measurement scale is intended for continuous data.

How can quantitative data be collected?

There are several methods by which you can collect quantitative data, which include:Experiments.Controlled observations.Surveys: paper, kiosk, mobile, questionnaires.Longitudinal studies.Polls.Telephone interviews.Face-to-face interviews.

What is an example of continuous quantitative variable?

A quantitative variable can be either continuous or discrete. A continuous variable is one that in theory could take any value in an interval. … Examples of continuous variables are body mass, height, blood pressure and cholesterol.

What is continuous qualitative data?

Qualitative Data are not numbers. … Continuous Data are numbers that may take on all sorts of decimal or fractional values. For example, your weight may be measured precisely as 92.234 kilograms.

What is the advantage of using a continuous variable vs a categorical variable?

As demonstrated above, treating an experimental variable as continuous rather than categorical during analysis has a number of advantages. First, it will generally have greater statistical power. Second, because fewer parameters are used to describe the data, it is more parsimonious.

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.

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.
