Frequently Asked Questions
What's the difference between mean, median, and mode?
Mean is the average, median is the middle value, and mode is the most frequent value. Each measure provides different insights about your dataset.
When should I use median instead of mean?
Use median when your data has outliers that might skew the mean. Median is more robust to extreme values and better represents typical values in skewed distributions.
Can I calculate statistics for decimal numbers?
Yes! This calculator works with both whole numbers and decimals. Simply enter them separated by commas like: 1.5, 2.75, 3.25
