Question from Sunni:

I'm working on a graph and I need to find the percentage of increase from one figure to another. How do I do that? For instance our department started with a workload of 1773 in jan and ended with 341 in Dec. In addition to that we received 2088 new items from Jan - Dec with an average of 5 workers. How do I find the percentage of increased productivity if any?

Hi Sunni,

You can calculate percentage change using the expression in Stephen's response to an earlier question. If the percentage change is positive then it is a percentage increase. The challenge in your question is how to measure productivity. Once you know that you can calculate productivity is January and December and then use Stephen's expression. How you measure productivity is not a mathematics question but a management question.
