uTo calculate the mean of values of specified frequency (Mean)
This procedure uses two lists: one that contains values and one that contains the
number of occurrences of each value. The frequency of the data in Cell 1 of the first
list is indicated by the value in Cell 1 of the second list, etc.
• The two lists must contain the same number of data items. Otherwise, an error
(Dim ERROR) occurs.
