Practice question · Multiple choice
A kinematics experiment gives m/s² rather than 9.81. What should be checked before concluding the measurement is simply imprecise?
Hints
- Ask what random scatter would look like across ten trials.
- Would it always land below the true value?
Show the answer
C. Whether the deviation is one-sided across every trial
Why
Scatter goes both ways; bias does not. A consistently low is a clue about the apparatus, and treating it as noise discards the most informative thing in the data.
