The numbers are 2.1, 2.2, 2.6, 2.3 The accepted density is 2.702
2.3 – 2.702 Percent error = x 100% = - 10% 2.702 Method B: 2.700 - 2.702 Percent error = x 100% = - 0.07% 2.702 Remember that percent error can be positive or negative, indicating whether the experimental value is too high or too low compared to the accepted value. c Calculate the standard deviation for each set of data. The average value for Method A is 2.3 g/cm and the average value for Method B is 2.700 g/cm. Method A: Method B: 0.05 An error has been detected in your answer.
