940 Chapter 29 Statistics and probability distributionsThe number of measurements made is6 +9+3+7+4 = 29. So,mean =x= 11029 = 3.79Example 29.4 illustratesageneralprinciple.If valuesx 1,x 2,...,x noccur with frequencies f 1, f 2,..., f nthen∑xi fx = ∑ ifiEXERCISES29.51 Engineersinadesigndepartmentareassessedbytheirleader.

29.6 Standard deviation 94129.6 STANDARDDEVIATIONAlthoughthemeanindicateswherethecentreofasetofnumberslies,itgivesnomeasureofthespreadofthenumbers.Forexample, −1,0,1and −10,0,10bothhaveameanof0 but clearly the numbers in the second set are much more widely dispersed than thoseinthe first. Acommonly used measure of dispersion isthestandard deviation.Let x 1,x 2,...,x nbe n measurements with a meanx. Then x i−x is the amount bywhichx idiffers from the mean. The quantityx i−x is called the deviation ofx ifromthe mean. Some of these deviations will be positive, some negative. The mean of thesedeviations is always zero (see Question 3 in Exercises 29.6) and so this is not helpfulin measuring the dispersion of the numbers. To avoid positive and negative deviationssumming to zero the squared deviation is taken, (x i−x) 2 . The variance is the mean ofthe squared deviations:variance =∑ (xi −x) 2nandstandarddeviation = √ varianceStandard deviation has the same units as thex i.Example29.5 Calculate the standarddeviation of(a) −1,0,1(b) −10, 0,10Solution (a) x 1= −1,x 2= 0,x 3= 1.Clearlyx=0.x 1−x=−1 x 2−x=0 x 3−x = 1variance = (−1)2 +0 2 +1 23= 2 3standard deviation =√23 = 0.816(b) x 1= −10,x 2= 0,x 3= 10. Againx=0andsox i−x=x i,fori=1,2,3.variance = (−10)2 +0 2 +10 2= 2003 3√200standard deviation =3 = 8.165As expected, the second set has a much higher standard deviation than the first.
