Let say I assign a random amount of tasks to my employees and after a month, I want to check who is more "productive" based on the task they'd finished but, I think is not fair to give a 50% to someone who had finished 4 tasks of 8 assigned compared to someone who had finished 28 of 95 assigned tasks.
Something similar to this?
\begin{array} {|r|r|r|r|} \hline Employee &Assigned &Finished &Percent \\ \hline Employee 1 &95 &28 &29.47 \\ \hline Employee 2 &67 &22 &32.84 \\ \hline Employee 3 &91 &37 &40.66 \\ \hline Employee 4 &8 &4 &50.00 \\ \hline Employee 5 &92 &51 &55.43 \\ \hline Employee 6 &108 &63 &58.33 \\ \hline Employee 7 &77 &47 &61.04 \\ \hline Employee 8 &67 &44 &65.67 \\ \hline Employee 9 &74 &54 &72.97 \\ \hline Employee 10 &62 &48 &77.42 \\ \hline \end{array}
What could be the correct operation to give a fair percent?
Weighted average, or with a bit of markup and margin possibly change percentages however you like. The problem is, we have nothing to weight with, except, amount of tasks completed with this information.
