Review Questions for September 23
... Assume we have a dataset in which the median of the first attribute is twice as large as the mean of the first attribute? What does this tell you about the distribution of the first attribute? What is (are) the characteristic(s) of a good histogram (for an attribute)? Assume you find out that two at ...
