This is an interesting mathematical question I came up with. I would like to know a NORMAL amount of keys that should be on a single key ring. (My parents both have a janitor's-mass of keys on their keyrings. They even have the last 2 keys that went to our house still on there!) So, I would like as many people as possible to reply to this, and I'll put it into a spreadsheet (hopefully :) ) and post up a graph of the results!

i have 6 keys. house, sisters apartment, keys for work, po box and car

I have four - house key for back home, stairwell key and room key for the dorms, and mailbox key.

I should probably know this without having to count...6, I have 6 keys.


Front door key.

Two lockbox keys.

Bottle opener (the key to happiness). 

And, lastly, a mystery key which I don't remember ever adding. I have no idea what this key could possibly open.

Mailbox, work drawers', friend's drawers, dad's house, mom's house, apartment key, pool key, car key. 

8. 8 keys, ah ah ah. 

My ring has 3 and Obi-Wan Kenobi. My mom has the last 3 keys we've had to our house, her car keys, the door to her parents house a thousand miles away, a key to the mailbox, to the garage, a key to all the bedrooms in the house, a key to the pantry, and 5 mystery keys her and I both don't know where they go to. So that's 17 keys. My dad has keys to the house, each of the two cars he drives, keys to all kinds of doors at work (about 4), clock winding keys, a key to open the drawer on his desk, a mailbox key, keys to his room, and a key to the garage. That's 12. My brother has 2 keys. So far we have:

2, 2, 3, 4, 6, 6, 6, 8, 12, 17.

The mean is about 7, the median is 6, the mode is 6. So it seems to me that 6 keys is the most normal amount of keys. But my parents have 2 or 3 times the normal amount! If more data trickles in, I'll post up something more. But yeah, people aren't replying to this that fast... ;D

On my house keys i've got four on my work keys i've about 45.

You some kinda of school teacher or janitor! :D

Yes teacher my College seems to have a different key of each class room
