Frequently Asked Questions
Mean vs median?▼
Mean is the average. Median is the middle value — better for skewed data with outliers.
When is mode useful?▼
Mode shows the most frequent value — useful for categorical or discrete data.
What does standard deviation tell me?▼
How spread out values are. Low SD = clustered near mean; high SD = dispersed.
How do I enter data?▼
Separate numbers with commas, spaces, or newlines.
Does it handle negative numbers?▼
Yes.
Population vs sample variance?▼
This calculator uses population variance (divide by n). Sample variance divides by n-1.
What if I have outliers?▼
Compare mean and median — large gap suggests outliers affecting the mean.
Can I use this for grades?▼
Yes — enter all scores to get average, median, and spread.
How many data points do I need?▼
At least 1 for mean; 2+ recommended for meaningful variance and mode.
Is data sent anywhere?▼
No — processed entirely in your browser.
