Weighted Average Calculator with option to calculate the average for selected rows only

Here is another version of the Weighted Average Calculator. The meaning of weighted average is best explained by the examples given here. This version allows the user to select data rows for calculation of the weighted average. This is specially useful for determining the weighted average of subgroups within the list or of any combination of data in the list. If no rows are selected or if only one row is selected the calculator will calculate the weighted average for the whole list of data. Otherwise, when two or more rows are selected the calculator will calculate the weighted average for the selected rows only. Please click on the Add Rows button to add more entries. The number of decimal places for the calculated average can be specified (The default value is 5).
