Analysing a binary variable
Center and Dispersion (n.a.)
As mentioned in the previous section, with only two categories the main interest is only in two percentages, which we can simply write in one line. Although we could determine as a measure of central tendency the mode, and also measures of dispersion, these are usually not explicitly mentioned and calculated if you only have two categories. They will be discussed in the section of center and dispersion for a nominal variable, available here.
The next section is of interest: Testing if the percentages are different.
