1.I have two apples, one banana, one cherry. Does it make sense to calculate the "average" of these things? Would you code that as a factor or numeric value in R?

2.I have four quiz scores: 94,93,85, and 0. What is the mean (average) of my quiz scores? Would you code this as a factor or a numeric value in R?

3.In another class, I received these grades on my quizzes: two As, one B, and one F. what is the mean (average) on my grades? Would you code that as a factor or numeric value in R?

4.How would you explain the difference in mean values obtained in #2 and #3 above?
