Question

The sum of the Female category represents the number of _____ surveyed. ?

The accompanying data were collected from a statistics class. The first row gives the variable,
and each of the other rows represents a student in the class. What do the numbers 1 and 0
mean for the variable Female in the table (which is coded categorical data)? Often, it does not
make sense, or is not even possible, to add a categorical variable. Does it make sense for
Female? If so, what does the sum represent?

The number 1 indicates that the subject is female, while the number 0 indicates that the
subject is not female. It does make sense to add a categorical variable for Female,
since it represents a quality of the object of interest. The sum of the Female category represents
the number of females surveyed.
