Accuracy of Answers

Converting fractions to decimals: Use at least two but no more than four decimal places.  If a fraction exactly equals a number with just one decimal place, you can leave it as one decimal place. 

Computing basic statistics: Use at least one, but at most two more decimal places than is in the original data.  If the result is exact at the same number of decimal places as the original data, you can leave it as is.  If you use three or more decimal places than is in the original data, you will lose points for being too accurate.
