Statistics Help

Input your dataset to see a full statistical profile. We automatically calculate central tendency (mean/median/mode) and dispersion (range/std dev).

Mean: Arithmetic average.
Median: Positional middle.
Range: Absolute spread.

If your Mean and Median are very different, your data is likely "skewed" by extreme outliers. The median is usually the more reliable "typical" value in these cases.

Standard deviation measures how much the values differ from the mean. A small standard deviation means the data is tightly clustered, while a large one means it is widely spread.
