Two different scientists measured the speed of light four times.
Accepted value of speed of light =3.00*108m/s
Which had greater accuracy? Which scientist had greater precision? Explain.
The closer the values of a measurement are to each other, the greater the precision.
Accuracy is how close the values accepted value
2. The attempt at a solution
Scientist B has greater accuracy because the average of scientist B is closer to the accepted value.
Scientist A has greater precision because the numbers are close to each other than scientist B.
I'm not sure if scientist A has greater precision. The first measurement for scientist A 3.80*108m/s is not close in value to the other measurements. But the rest of the values for scientist A seem to be closer.
