precision and measurement?
Which of the following examples shows the most precision?
1. 14 grams, 16 grams, 20 grams
2. 0.012 mg, 0.019 mg, 0.024mg
3. 22 cm, 25 cm 28 cm
4. 0.791 mg, 0 .793 mg 0 .795 mg
without sitting at a computer or punching it into a statistical calculator myself, I would do the following: find the mean of each set of data and also find the standard deviation….most calculators will do this pretty easily after punching in the numbers. Now, find the relative standard deviation for each set by dividing the standard deviation by the mean and multiplying by 100%…..which ever set gives you the smallest percentage is the most precise.
