Average Calculator: Mean, Median, Mode, Std Dev

Your details

Arithmetic is the standard average. Geometric suits growth rates. Harmonic suits rates and speeds. Weighted lets you assign importance to each value.
Separate values with commas, spaces or new lines.

Arithmetic mean = 30

  • The arithmetic mean of your 5 values is 30.
  • Your mean and median are close, so the average is a fair summary of this dataset.
  • The population standard deviation is 14.1421, measuring how spread out the values are around the mean.
  • The range is 40 (max 50 minus min 10).

Next stepTo measure spread, check the standard deviation above. Switch to geometric or harmonic mode for rate or ratio data.
