Solution

Type of Bias Identification

In the given scenario, the scales consistently read 0.5 grams below the actual weight. This systematic error indicates a consistent deviation from the true value, which is characteristic of a negative bias.

Explanation of Bias

Bias refers to a systematic error that affects the accuracy of measurements. In this case:

  1. The scales are calibrated improperly, resulting in all measurements being reduced by 0.5 grams.
  2. This consistent underestimation leads to a systematic discrepancy, which means every reading is less than the actual weight.
  3. Since the performance of the scales always leads to values that are lower than the truth, this is classified as a negative bias.

In conclusion, the type of bias present in this scenario is negative bias, as all measurements are systematically lower than the actual values.
