A matrix displaying frequencies for combinations of two categorical variables, with rows and columns representing categories. Categorical Variable
A data type with distinct groups or categories, such as grade level or car ownership status. Frequency Table
A chart listing counts for each category of a single variable, summarizing how often each occurs. Cell Frequency
The count found at the intersection of a specific row and column in a contingency table, representing a unique category combination. Row Total
The sum of all frequencies in a row, indicating the total count for a specific category across another variable. Column Total
The sum of all frequencies in a column, showing the total count for a specific category across another variable. Grand Total
The overall sum of all frequencies in a contingency table, representing the total number of observations. Marginal Probability
The likelihood of a single category occurring, calculated using row or column totals divided by the grand total. Joint Probability
The chance of two events happening together, found by dividing a cell frequency by the grand total. Conditional Probability
The probability of one event occurring given that another event has already occurred, using a cell frequency over a row or column total. Category Total
The total count for a specific group, found in the row or column totals of a contingency table. Intersection
The point in a contingency table where a specific row and column meet, representing a unique combination of categories. Survey
A method of collecting data from individuals, often used to gather information for contingency tables. Event
A specific outcome or category of interest in probability calculations, such as being a senior or driving a car.
