Here, valuerange refers to the cells containing the observed values (the numbers in the "value" column). frequencyrange refers to the cells containing the number of times each value is observed (the numbers in the "frequency" column). You can also find the mean of grouped data from a relative frequency distribution. The formula is even simpler:
