In a MySQL (5.1) database table there is data that represents:

  • how long a user takes to perform a task and
  • how many items the user handled during the task.

Would MySQL support correlating the data or do I need to use PHP/C# to calcuate?

Where would I find a good formula to calculate correlation (it's been a long time since I last did this)?
