Check Your Progress I: Find the range of the numbers of ounces dispensed by Machine 2 in Table 4.5.We introduced three types of average values for a data set - the mean, the median, and the mode. Somecharacteristics of a set of data may not be evident from an examination of averages. For instance, consider asoft-drink dispensing machine that should dispense 8 oz. of your selection into a cup. Table 4.5 shows data for twoof these machines.TABLE 4.5: SODA DISPENSED (ounces)Machine 1Machine 29.528.016.417.9910.077.955.858.038.158.02X = 8.0X = 8.0
