Productivity is measured by the amount of output per unit of input.
In this case, the inputs will be the hours spent doing research and writing their essays. Output will equal the amount of pages written.
Marci spent 8 hours and wrote a 26 page long report, so her productivity = 26 pages / 8 hours = 3.25 pages per hour
Jack spent 20 hours and wrote a 26 page long report, so his productivity = 26 pages / 20 hours = 1.3 pages per hour
Marci is much more productive in terms of hours spent doing and writing, and how long the report is.
The problem with this type of analysis is that we do not know if Marci's report was good or bad, and the same applies to Jack's. Since we do not know what grade they got, we cannot be sure how effective their work was.
