Suggestions for my science survey?

Question

I'm making a survey about how much you talk on your cell phone for my science project. I'm not allowed to ask questions with yes/no answers because the answers have to be numbers so I've been stuck so far. So far I've come up with

1.How many calls do you make on your cell phone in a day?
a.
___ 0-1
___ 2-3
___ 4-5
___ 5-10

2.How many calls do you make on your cell phone every week?
a.
___ 0-3
___ 4-6
___ 7-9
___ 10 or more

3.How long are your calls usually?
a.
___ 1-2 minutes
___ 3-5 minutes
___ 6-10 minutes
___ 10 minutes or more


4.How long was your longest call on your cell phone?
a.
___ 15-30 minutes
___ 30-45 minutes
___ 45-60 minutes
___ more than an hour


Please leave suggestions of other questions I might be able to use!

BTW. questions have to have answers that are numbers cause my teacher won't allow me to ask questions like...

do you talk on your cell phone atleast once a day?

Answer 1

Hmm, possible questions: How many cell phones do you have in your household?: none, 1-2, 3-4, 5 or more. That's the only question I can think of for now.

I hope that helps you;) Good luck with your project.

Answer 2
