Movie DVDs owned by students


The variable Dvds in the student dataset contains the number of movie DVDs owned by students in the class.

1. Construct a histogram of this variable by use of the hist command.

2. Summarize this variable by the summary command.

3. Use the table command to construct a frequency table of the individual values of Dvds that were observed. If one constructs a barplot of these tabled values by use of the command 


barplot(table(Dvds))

one will see that particular response values are very popular. Is there 
 any explanation for these popular values for number of DVDs owned?
