Frequently Asked Questions
What's the difference between mean, median, and mode?
Mean = average (add all values, divide by count). Median = middle value (line them up, pick the one in the center). Mode = most frequent value. Each tells you something different about your data.
How do I interpret standard deviation?
It shows how spread out your data is. Small standard deviation = data points are close to the average. Large standard deviation = data is all over the place.
What is variance?
It's the square of standard deviation. Measures how far data points are from the mean on average. Mostly used in more advanced statistics.
How do I use this calculator?
