Joint Frequency
Each entry in a two-way table
Joint frequency refers to the number of times that two variables appear together in a dataset. In other words, it is the frequency of a specific combination of values for two variables.
For example, consider a dataset that contains information on the age and gender of a group of people. The joint frequency for a 40-year-old male would be the number of times that a person with those particular characteristics appears in the dataset.
Joint frequencies can be useful in statistical analysis, particularly in relation to contingency tables. A contingency table displays the joint frequencies of two categorical variables in tabular format, allowing researchers to assess possible associations and dependencies between the variables.
In summary, joint frequency is a measure of the occurrence of specific combinations of values for two variables in a dataset which helps in understanding the relationship between the two variables.
