Precision and Accuracy

Accuracy

  • How close measurement is to true value

  • Closer the result= more accurate it is

  • Results= more accurate by repeating readings and carefully designing experiment

Precision

  • How close repeated measurements are to each other

  • Closer the measurements= more precise

  • Made more precise by using measuring devices with smaller scale readings or increasing the value of the reading compared to the smallest scale division
