I have another question concerning one of previous posts: Stem-Leaf Display
In the textbook, in a later paragraph, they remark about how "...there are no observations that are unusually far from the bulk of the data (no outliers), as would be the case if one of the 26% values had instead been 86%."
Isn't the $4\%$ value particularly distant from the bulk of the data? And how would having an additional $86\%$ value in place of one of the $26\%$ values affect anything? Also, is the representative value always found in the place where the bulk is, where most of the data is concentrated?
Another remark the author makes:
"The most surprising feature of this data is that, at most colleges in the sample, at least one-quarter of the students are binge drinkers. The problem of heavy drinking on campuses is much more pervasive than many had suspected."
Wouldn't it actually be nearly $50\%$ of students at universities be binge drinkers, because that is where the values are concentrated?
