The following equation can be used to calculate the expected frequency of a contingency table.
E =( Ri + Cj )/ N
- Where E is the expected frequency
- Ri is the total in the ith row
- Cj is the total in the jth column
- N is the grand total
In the case of a contingency table, this expected frequency calculation must be performed on each sell. So if you have 32 rows and columns, you will need to do the calculation 32 times.
An expected frequency is a term used in statistics to describe the probability count of a contingency table calculation.
An expected frequency is calculated using the formula above for each cell.
