When multiplying or dividing, and using sig figs, the final answer can have only as many sig figs as the measurement with the LEAST number of sig figs. Example: 6.3 cm x 2.2 cm = 13.86 cm2 according to my calculator. Using sig figs, my answer would . be ~ 14. I must round my answer to 2 sig figs because each measurement in the problem, the

Jul 02, 2010 · First we need the mean and standard deviation. Learn to use your calculator or Excel to get these values. You should get x(bar) = 0.148 and s = 0.034. Since we have 6 values, the degrees of freedom is N – 1 = 6 – 1 = 5. We get the values of t from Table 4-2. For a 90% confidence level, t = 2.015. For 99% t = 4.604.

It needs to be emphasized that to say a certain digit is not significant does not mean that it is not important or can be left out. Though the zero in a measurement of 140 may not be significant, the value cannot simply be reported as 14. An insignificant zero functions as a placeholder for the decimal point.
