Scientific Method Flashcards
1
Q
What is validity?
A
Is whether an experiment tests the hypothesis
2
Q
What is reliability?
A
The repeatability of an experiment with consistent results
3
Q
What is accuracy?
A
The closeness to the true value or the LOBF
4
Q
What is precision?
A
The repeatability of a measurement
5
Q
What are design errors?
A
Errors that come from planned method which lowers validity
6
Q
What are random errors?
A
Errors that are inconsistent which lowers reliability
7
Q
How can random error/reliability be improved?
A
It is improved by increasing the number of trials and removing outliers
8
Q
What are systematic errors?
A
Are consistent errors which lower accuracy
9
Q
How can systematic error/accuracy be improved?
A
It is improved by calibrating equipments and using them for the correct purpose
