## Average calculations are NOT correct (solved) 8 years 4 months ago #1258

 Micha OFFLINE New member Posts: 2 I have a major problem with the 'averages'. Please look at this example. The first student had a 2/10 for his first test. His second test was a 18/20. Together it's 20/30. The average should be 66,66% or 6.6/10. But the calculus (average) says it's 5.50. What went wrong? How do I get the right average.

 bert OFFLINE Admin Posts: 3287 Thank you received: 624 Welcome Micha, From what I see , it seems correct, (2/10 + 18/20) /2 = 11/20 which is 5.50 I think what you did wrong was 2/10 +18/20 , that equals 22/20, not 20/30 If something is still not clear please let me know!

 Micha OFFLINE New member Posts: 2 Thank you for the quick answer! But I what I wrote was what I meant; 2/10 + 18/20= 20/30. One test is on 10 and the other on 20. If it were to be 4/20 + 18/20 then the average would be 50%. But I want the first test to be on 10 and not on 20. In the last case, the average is not 50%. Look at the example of the other student: same problem. I have a lot of tests that vary in 'weight' - so they can't be brought back on the same level: f.i. an exam (100 points) is not the same as a reading exercise (5 points). In the actual 'calculus' system of iDoceo the reading exercise would be changed to 100 points. The average would then be based on 2 tests on 100 points. So my question stays: how can you solve the 'average' problem? thx The administrator has disabled public write access.

 bert OFFLINE Admin Posts: 3287 Thank you received: 624 Micha, There is actually a faster way that does not involve an intermediate column. Here the image. The configuration From 0 to 30 stays the same as stated in previous post. Please take a moment to add or update your rating for iDoceo 7 teacher gradebook so that we can continue working on it.
