1
New cards

  • state what measurement errors cause


  • uncertainties


2
New cards

  • state the two types of errors


  • systematic

  • random


3
New cards

  • define systematic error


  • an error caused by an incorrectly calibrated instrument or an incorrect experimental method


4
New cards

  • state the effect a systematic error has on measurements


  • all measurements are affected

  • loss of accuracy


5
New cards

  • state how to reduce systematic errors


  • calibrate the instrument correctly

  • adjust the experimental method


6
New cards

  • define zero error


  • a systematic error caused by an instrument giving a non-zero reading when the true value is zero


7
New cards

  • define random error


  • an error caused by uncontrollable factors which change an instruments readings


8
New cards

  • state the effect a random error has on measurements


  • not all measurements are affected

  • loss of precision


9
New cards

  • state how to reduce random errors


  • repeat the measurement readings to gain an average
