What does high bias indicate about measurement results?

High bias in measurement results refers to a systematic error that consistently skews the outcomes in one direction, leading to a significant difference between the measured value and the true value. When measurements exhibit high bias, it often indicates that the results are consistently inaccurate because the equipment or process is flawed in a manner that consistently overestimates or underestimates the actual radon levels.

This concept is important in radon measurements, as accurate results are crucial for assessing health risks and ensuring safety. A high bias can undermine the integrity of the measurement process, leading to misguided decisions and actions concerning radon mitigation. Understanding that high bias indicates a consistent inaccuracy helps technicians identify when recalibration or maintenance of equipment may be necessary.

In contrast, the other options discuss aspects of measurement variability or precision that do not directly relate to the idea of bias, which is fundamentally about systematic error rather than random error or distribution of measurement.
