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
