Bias and Uncertainty

This applet interactively demonstrates the bias and uncertainty of an estimator.

How to use the applet

  1. Set the bias with the left slider to a positive or negative value. Observe the location of the new sample (blue crosses) relative to the true value (red circle).
  2. Set the uncertainty with the right slider to a nonnegative value. Observe the spread of the new sample.
