Can a variable be categorical and discrete?
Categorical variables are also known as discrete or qualitative variables. Categorical variables can be further categorized as either nominal, ordinal or dichotomous. Nominal variables are variables that have two or more categories, but which do not have an intrinsic order.
Is discrete categorical or quantitative?
Quantitative variables can be classified as discrete or continuous. Categorical variables contain a finite number of categories or distinct groups. Categorical data might not have a logical order. For example, categorical predictors include gender, material type, and payment method.
Can quantitative variables be discrete?
A quantitative variable can be either continuous or discrete. A continuous variable is one that in theory could take any value in an interval.
Is categorical data discrete?
Typically, any data attribute which is categorical in nature represents discrete values which belong to a specific finite set of categories or classes. These are also often known as classes or labels in the context of attributes or variables which are to be predicted by a model (popularly known as response variables).
Are all qualitative variables discrete?
Variables that can only take on a finite number of values are called “discrete variables.” All qualitative variables are discrete. Some quantitative variables are discrete, such as performance rated as 1,2,3,4, or 5, or temperature rounded to the nearest degree.
Can a variable be both continuous and categorical?
We will assume a continuous dependent variable, as we have throughout. Models in which there are both continuous and categorical variables are often called analysis of covariance or ANCOVA for short.
What are discrete variables examples?
A discrete variable is a variable whose value is obtained by counting. Examples: number of students present. number of red marbles in a jar. number of heads when flipping three coins. students’ grade level.
What type of data is discrete?
Discrete data is a count that involves integers — only a limited number of values is possible. This type of data cannot be subdivided into different parts. Discrete data includes discrete variables that are finite, numeric, countable, and non-negative integers.
Is quantitative variable discrete or continuous?
Quantitative variables may be discrete or continuous. Discrete variables can only take on a limited number of values (e.g., only whole numbers) while continuous variables can take on any value and any value between two values (e.g., out to an infinite number of decimal places).
What makes a variable discrete?
A discrete variable is a variable whose value is obtained by counting. Examples: number of students present. number of red marbles in a jar.
What are discrete variables?

Is qualitative data discrete or continuous?
Qualitative vs Quantitative Data can be qualitative or quantitative. Quantitative data can be Discrete or Continuous: Discrete data can only take certain values (like whole numbers) Continuous data can take any value (within a range)
Is the data discrete or continuous?
Discrete data is the type of data that has clear spaces between values. Continuous data is data that falls in a constant sequence. Discrete data is countable while continuous — measurable. To accurately represent discrete data, the bar graph is used.
What is one example of a discrete variable?
As opposed to a continuous variable, a discrete variable can assume only a finite number of real values within a given interval. An example of a discrete variable would be the score given by a judge to a gymnast in competition: the range is 0 to 10 and the score is always given to one decimal (e.g. a score of 8.5).
What are categorical discrete and continuous variables?
What are categorical, discrete, and continuous variables? Quantitative variables can be classified as discrete or continuous. Categorical variables contain a finite number of categories or distinct groups.
What is the difference between categorical and quantitative data?
Quantitative variables can be classified as discrete or continuous. Categorical variables contain a finite number of categories or distinct groups. Categorical data might not have a logical order.
What are the types of quantitative variables?
Quantitative variables When you collect quantitative data, the numbers you record represent real amounts that can be added, subtracted, divided, etc. There are two types of quantitative variables: discrete and continuous.
What is the difference between categorical and discrete predictors?
For example, categorical predictors include gender, material type, and payment method. Discrete variables are numeric variables that have a countable number of values between any two values. A discrete variable is always numeric. For example, the number of customer complaints or the number of flaws or defects.
