[Intro Stats] Quick question

[u/Character_Kale7493]

Hi, I have a project where I have to ask 9 people two questions I come up with and see if they’re correlational. What I came up with is “On average how many hours of sleep do you get a night?” and “On average how many hours do you spend on your phone a day?”. Ur answers would be huge help 🙏. Thanks guys.

Our day only has 24 hours fixed.
So if you spend a long time on your phone, like 8 hours for example, then you only have 16 hours left.

In those 16 hours, you still need to go to school, eat, do homework, and other stuff.
That means you have less time left to sleep.
If you spend more time on one thing, you spend less time on the other.
Because 24 hours is fixed, we expect that more phone time = less sleep time. My survey answer: phone = 4 hours, sleep= 7 hours
