Practice question · Multiple choice
An experimental result is reported as m/s². Why is the uncertainty part of the result rather than an admission attached to it?
Hints
- Ask whether agrees with .
- Now answer it again knowing the uncertainty is , then .
Show the answer
B. Because without it the number cannot be compared with anything
Why
Agreement is a statement about intervals. The same central value agrees or disagrees depending on the uncertainty, so the uncertainty IS the claim.
