How can combining uncertainties from multiple measurements affect the overall uncertainty of a result?.
- A.It always increases the overall uncertainty.
- B.It always decreases the overall uncertainty.
- C.It can either increase or decrease the overall uncertainty.
- D.It has no effect on the overall uncertainty.
Model answer
What a good answer should say
- It can either increase or decrease the overall uncertainty.
Explanation
Why this works
