Random Errors Flashcards
(4 cards)
1
Q
What is a random error and give examples of what causes them?
A
Errors made by person carrying out experiment.
Examples: Parallax error, Reaction time, Variation in conditions (e.g. temperature of room)
2
Q
What is parallax error?
A
Caused bys tudent not reading measurement at eye level. Leads to inaccurate readings.
3
Q
How can experiments invloving reaction time lead to random error?
A
Different students have different reaction times. This introduces random errors.
4
Q
How do we reduce the effect of random errors?
A
Take more measurements
Calculate a mean
