Categorical variables measure characteristics or qualities that can be divided into distinct categories or groups. These variables represent non-numeric data, such as gender, color, or type of vehicle, where each category is mutually exclusive. They help in organizing data into meaningful classifications, allowing for analysis of patterns and relationships within the data. Categorical variables can be further classified into nominal and ordinal types, depending on whether the categories have a natural order or ranking.

Does a crosstabulation have to have both categorical and quantitative?
No, a crosstabulation does not have to include both categorical and quantitative variables. It is primarily used to summarize the relationship between two categorical variables. However, quantitative variables can be categorized into groups or bins to create a crosstabulation, but it's not a requirement.
What is categorical data?
Categorical data is the statistical data type consisting of categorical variables or of data that has been converted into that form, for example as grouped data.
What SPSS procedures can be used for data screening of categorical variables?
variance
How many variables does a t test measure?
A t-test typically measures two variables: one categorical independent variable with two levels (groups) and one continuous dependent variable. It assesses whether there is a statistically significant difference in the means of the continuous variable between the two groups.
What is the difference between continuous and categorical independent variables?
A categorical variable (also known as a discrete variable) is one whose range is countable; e.g. the variable answ has values [yes, no, not sure]. answ is a categorical variable with range 3.A continuous variable is one which is not categorical; e.g. weight is a continuous variable which can take any value between 0 and 1000 kg (say) for a human being.
What measure of central tendency applies to categorical variables?

What is the contingency table?
A contingency table is a display of the frequency distribution of two or more categorical variables. It shows the relationship between the variables by organizing the data into rows and columns, with the intersection cells showing the frequency of each combination of variables. Contingency tables are commonly used in statistics to analyze the association between categorical variables.
Is age a categorical variable?
Age is acontinuousvariable because it can bemeasured with numbers. A categorical variable deals with nominal variables example male or female, political view, etc
What are categorical variables?
Categorical variables take on a limited and at times a fixed number of value possibilities. If in fields such as Compute Science or Mathematics, they are referred to as enumerated types. In some cases possible values of a variable may be classified as levels.

What is analysis of covariance used for?
Analysis of covariance is used to test the main and interaction effects of categorical variables on a continuous dependent variable, controlling for the effects of selected other continuous variables, which co-vary with the dependent. The control variables are called the "covariates."
