Variance Z Y YY 2 139 SY n 1 Standard deviation SY s Why does the formula for a variance have us divide by 711 instead of n First note that if we were taking the variance 6 of an entire population 2 Y 7f 11 The reason we divide by n 71 for s and sz is that we are trying to use the sample data to estimate 6 To see why dividing by 71 would not work consider the case where n 1 What is the sum of squared deviations about the mean Since the mean equals your one observation Your one squared deviation is ALWAYS equal to zero So if you divided the sum of squared deviations 0 by n 1 you would estimate 6 as zero which is not appropriate In fact where you have one case you have ABSOLUTELY NO INFORMATION about the variance The formula we use dividing by 711 would give us 00 This is unde ned which is appropriate since we have no information By contrast if we divided by n we would get 01 This would lead us to erroneously estimate the population variance as zero Coefficient of Relative Variation see Norusis p 66 standard dev 100
