Frequently Asked Questions
What is the difference between average and weighted average?
Average treats all values equally, while weighted average assigns different importance levels (weights) to each value.
How do I calculate weighted average?
Multiply each value by its weight, sum the results, then divide by the total of all weights: Σ(Value×Weight) ÷ Σ(Weights)
What is median?
The median is the middle value in a sorted list of numbers. For even counts, it's the average of the two middle values.
Is my data stored?
