Explanation:
Time to run a marathon, height, size of flat–screen television, hours spent studying core, and calories in desserts are quantitative variables.
Shoe color, number on an athlete’s jersey, gender, and ice cream flavor are categorical/qualitative variables and need to be transformed into dummy variables. Note that although athlete’s jerseys have numbers, those values cannot be interpreted as real numbers.
