What is the difference between an average and a score?
Before getting into the calculations, there is a fundamental distinction you need to keep in mind:
-
Averages for people (evaluated employees, departments, workplaces…) work as true averages: the values for each person are added together and divided by the number of people. For example, a department's average is the sum of its employees' scores divided by the number of employees.
- Scores for question groups and subgroups are sums, not averages: the overall averages of their questions are added together without dividing. For example, if a group has 3 questions with averages of 3.50, 4.00, and 3.20, the group's score is 3.50 + 4.00 + 3.20 = 10.70.
💡 Why are group and subgroup scores summed rather than averaged? Because each question can have a different maximum score. By summing them, we reflect the real weight of each question within the group: a question worth up to 10 points carries more weight than one worth up to 2. If they were averaged, both would carry equal weight.
