In your own words, describe to someone who knows only a little statistics how to recognize when an observation is an outlier. what action(s) should be taken with an outlier?
(a) outliers are observed values far from the main group of data. in a histogram they are separated from the others by space.
(b) outliers must be looked at in closer context to know how to treat them. if they aremistakes, they might be removed or corrected. if they are not mistakes, you might do the analysis twice, once with and once without the outliers.
(c) outliers are observed values far from the main group of data. in a histogram they are separated from the others by space. outliers should be ignored because they can distort any calculations done and are not representative of typical values.
(d) outliers are the minimum and maximum values observed in a data set. they should be treated as any other value, as the term "outliers" is just another name for the minimum and maximum.
