Precision versus Accuracy

Cards in this group · 4

  1. C8.09.1Accuracy is the mean offset between estimated and true gaze
  2. C8.09.2Precision is the spread of repeated measures; the two can vary independently
  3. C8.09.3High precision with low accuracy looks stable but systematically offset
  4. C8.09.4The lower bound on target size is set by accuracy, not precision
