Frequently Asked Questions
When should I use simple vs. weighted average?
Use simple average when all values have the same importance (e.g., 5 exam scores). Use weighted average when some values matter more (e.g., an exam worth 40%, homework 30%, and participation 30%). The 'weights' indicate relative importance.
How do I interpret standard deviation?
Standard deviation indicates how spread out your values are from the average. A low deviation means values are very close to the average; a high deviation means there's a lot of variation.
Can I mix decimal and whole numbers?
Yes, you can enter any combination of decimals (8.5, 7.25) and whole numbers (9, 8). The calculator will automatically handle precision and display the result with two decimal places.
