My qualitative variables are people's age and people's job etc...
Because young people use the Internet a lot but old people are not use the Internet well.
Also, old people don't know how to use the Internet well.
Moreover, young people usually prefer use the Internet becuase they want to check fot facebook, chat with friends or do homework.
Also,while people work at the office, people always use the Internet.
However, if they off, they will not use the Internet.
Moreover, if Internet will be brokon or soemthing problem, they can not use the Interent.

Actually, I am confused frequencies.
What is exactly frequencies?
Also, how to describe frequency table?
I think that we have to gather research materials and then make chat.
