1. Different students in a class was asked to give their estimated volume of a liquid in a beaker. Student 1 give her estimate as 200 mL and 215 mL,190 mL, 195 mL and 230 mL for students 2,3,4, and 5, respectively . When the teacher poured the liquid into a graduated cylinder, she measured the volume as 208 mL. What is the percentage error of the estimated volumes from the beaker, taking the graduated cylinder measurement as the accepted value?
True Value = 1.20 g/cm3
Trials Lyla Geneve Joacquin
1 0.98 g/cm3 1.53 g/cm3 1.25 g/cm3
2 1.23 g/cm3 2.00 g/cm3 2.96 g/cm3
3 1.02 g/cm3 1.18 g/cm3 2.65 g/cm3
4 1.12 g/cm3 1.92 g/cm3 1.89 g/cm3
5 0.83 g/cm3 1.65 g/cm3 2.76 g/cm3
Describe the accuracy and precision of the given data.
Among the students , who committed the least error? Explain your answer
