The frequency distribution below represents the number of classes currently being taken by a sample of college students. Provide the missing values labeled a, b, and c on the table below, and then find the median, mode, and mean for the scores. Be sure to use appropriate symbols where necessary. Note that these scores were measured along a discrete scale of measurement, so the precise median (like the one you calculate for continuous variables) is not required.
