Collecting Data (VCE SSCE Physics): Flashcards

How closely measurements agree with each other

How close a measurement is to the true value

Smallest change the instrument can detect

Half the smallest marked interval

Consistent deviation in same direction from true value

Does NOT improve accuracy; shift remains

Take multiple measurements and calculate average

Should NOT be included; they are mistakes

Value $\pm$ uncertainty (e.g., $35 \pm 1 \text{ mm}$)

Successfully measures what it aims to measure
