Average questions
Simple or weighted average?
Simple when every value counts the same. Weighted when tests have different importance.
How many values fit?
Up to 200 per calculation, enough for full class lists.
Do zeros count?
Yes: 0, 10 and 10 average 6.67, not 10. If a value doesn't exist, leave its line out instead.
When is the average misleading?
Salaries of 2000, 2000, 2000 and 20000 average 6500, which nobody typical earns. For skewed sets the median (2000 here) describes the middle better — this tool reports the mean.
