Uncertainty Flashcards
What is accuracy?
How close a result is to the true value
What is precision?
How close repeated values are to one another
What are errors?
The difference between a result and the true value
What is uncertainty?
Estimate of the range of values within which the true values lie
What is absolute uncertainty?
Is the uncertainty of a measured object
What is the absolute uncertainty of time?
0.2-0.5s due to human reaction time
How do you calculate % uncertainty?
Absolute uncertainty/measured value
x100
How do you calculate % uncertainty of multiple readings
1/2 range / mean value
x100
How do you calculate % Uncertainty in gradients
Gradient of LOBF- Gradient of WALOBF/ Gradient of LOBF
x100
What would be the combined uncertainty of:
y= ab
a + b
What would be the combined uncertainty of
y= ab²
a + b + b
What would be the combined uncertainty of
y=ab/cd
a + b + c + d
