The accepted value of the melting point of pure aspirin is 135 °C. Trying to verify that value, you obtain 134 °C, 136 °C, 133 °C, and 138 °C in four separate trials. Your partner finds 138 °C, 137 °C, 138 °C, and 138 °C. (a) Calculate the average value and percent error for your data and your partner’s data. (b) Which of you is more precise? More accurate?
