1. Why are several readings taken for each physical quantity in an experiment?
2. A single reading taken with a meter stick for the length of a cylinder is 5.5 cm. What is the probable percent error in the reading?
3. The following readings were taken with a meter stick for the length of a cylinder: 5.5 cm, 5.3 cm, 5.4 cm, 5.5 cm and 5.6 cm. Calculate the standard deviation of the mean, the stand error and the probable percent error.
4. How many significant figures should be given in reporting the length of the cylinder in question 3?
5. If the radius of the cylinder in question 2 is 2.4 ± 0.2 cm and its mass is 32.6 ± 0.5 gm, what will be the probable percent error in the density of the cylinder? What will be the probable error in density? How many significant figures should be given in reporting the density?
