Calculate the weighted average of a dataset where some values contribute more than others.

Unlike a simple average, a weighted average takes into account the relative importance (weight) of each value.
Input the numbers you want to average in the 'Value' column.
Input the corresponding weight for each value in the 'Weight' column.
Use the 'Add Row' button to include more data points or the trash icon to remove them.
