Accurate But Not Precise
  • A straight line passing through the origin represents the true value for a line y = x
  • Every measured value is plotted so that it lies away from the line representing the true value (imprecision) but so that the line of best fit matches the line of true value (accuracy)
  • The concentric rings represent input with the true value at the center
  • The location of the measured values average the point exactly at the center of the concentric rings (accuracy) but are loosely packed around the target (imprecision)
