What is the fx column in a frequency distribution table?
The fx column in a Frequency Distribution Table is the frequency (f) multiplied by the Class Centre or score (x). If the score is 22. And the freqency for that score is 7. fx = 22*7 = 154 You can use the total of the fx column to find the mean. The total fx divided by the total frequency = Mean.
