Hopefully you can help me with this.
I am doing a questionnaire about internet use of children.
One of the questions is what kind of electronics they own. So, I've put in values:
1; Laptop / pc
4; Xbox / playstation / Wii
Though, some respondents said for example that they own a laptop (1) and a smartphone (2)
How do I add other values to the data overview. (so value 1 AND value 2)
Hopefully you can help me! Thanks
