For the following set of analyses of an urban air sample for carbon monoxide: 325, 320, 334, 331, 280, 331, 338 mg/m3, (a) determine the mean, standard deviation, median, mode, and range using Excels Descriptive Statistics. (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? I am not familiar with using Excel and keep making mistakes so would like someone to explain to me step by step how they got the solutions
