question: Discuss a suitable method to average the six values of the gradient and provide a final value

so, I have data values g, and the standard deviation of these measurements, and need to average these measurements based on the quality of the standard deviation so provide a more accurate value

Answer 1

1.Since the average values of pi obtained from both the algebraic analysis of the numerical data as well as the graphical analysis both are within 0.02 cm of the correct or actual value of pi, the measurement is accurate.

2. It is also clear that the standard deviation of the 6 numerical values which is determined to be 0.00075 is within 0.02 cm so that the measurement is precise.

3.By choosing a thinner string to measure the circumference of the circular object as well as choosing a ruler which can measure a length to a greater number of significant figures we can measure the value of pi more precisely and accurately.

The experiment clearly brings out or demonstrates the significance of and difference between the 2 important features of any experimental measurement-Accuracy and precision as the two are mostly thought to be the same.
