For the following set of analyses of an urban air sample for
carbon monoxide: 325, 320, 334, 331, 280, 331, 338 mg/m3
(b) calculate the coefficient of variation and RSD.
(c) is there any value in the above data set that can be discarded
as an outlier?
Homework Answers
mean = sum of terms/ total number of terms
= 325+320+334+331+280+331+338 /7
=2259/7
=322.71
S.D= 2.6901
coefficient of variation= S.D/mean
= 2.6901/322.71
=0.0083
RSD= COV×100%
= 0.0083×100%
=0.83%
C)- the value 280 is can be discarded as an outlier
