Five students had a mean score of 90 points on a test.
One test was scored incorrectly, and that particular test score was later raised by five points.
What is the new mean score?
:
The total value of all 5 students originally = 5*90 = 450
The corrected total value = 455
The corrected average: 455%2F5 = 91 is the new mean score
