What is the best way to represent the following formula as a graph?
Overall Score = 70% × [ 50% × Subfactor A + 20% × Subfactor B + 5% × Subfactor C + 50% × Subfactor D ] + 30% × [ 15% × Subfactor A + 50% × Subfactor B + 10% × Subfactor C + 15% × Subfactor D ]
For example, if: Overall Score =
70% × [
50% × 44% +
20% × 3.75% +
5% × 14.4% +
50% × 20.5%
] +
30% × [
15% × 10% +
50% × 10% +
10% × 16.67% +
15% × 25%
]Then, one way of possibly representing the data would be this way:
A pie chart with three layers; outer later is labelled “Overall Score” and represents the evaluated value of the formula previously mentioned; the 2nd inner layer shows the two fixed factors A and B with their fixed influences, 70% and 30%, respectively; and under each arch of the previously mentioned inner layers are sublayers, representing the subfactors, broken down to either completely fit or fit partially within the arches of the parent layer.
(Note that if all subfactors were 100% then the graph would be completely filled with no grey areas under factor A and factor B.)
However, is it a good graph? What are the pros and cons of this approach? And it is the best graph to use for the formula provided? Could a different graph work? Or is a graph even necessary?
Thanks for your feedback.
