Probability and contingency table
Did you know?
Contingency tables are a great way to classify outcomes and calculate different types of probabilities. These tables contain rows and columns that display bivariate frequencies of categorical data . Analysts also refer to contingency tables as crosstabulation (cross tabs), two-way tables, and frequency tables. Visa mer Contingency tables classify outcomes in rows and columns. Table cells at the intersections of rows and columns indicate frequencies of … Visa mer Joint probabilities are the probabilities that events occur together. For example, what is the joint probability of a Mac purchase by a female? … Visa mer Conditional probabilities are the probability that an event occurs given that another event has occurred. For example, given that a customer is female, what is the probability she’ll purchase a Mac? These probabilities … Visa mer Marginal probabilities are the probabilities that a single event occurs with no regard to other events in the table. These probabilities do not … Visa mer Webbcontingency table provides a way of portraying data that can facilitate calculating probabilities. The table helps in determining conditional probabilities quite easily. The table displays sample values in relation to two different variables that may be dependent or contingent on one another.

They are heavily used in survey research, business intelligence, engineering, and scientific research. They provide a basic picture of the interrelation between two variables and can help find interactions between them.
