Uncertainty in Measurements
Students often overlook the impact of measurement uncertainty on their results, assuming their measurements are perfectly accurate.
To fix this, students should always consider and state the possible sources of uncertainty in their measurements, such as equipment limitations or human error, and include these in their analysis.
