# AQA Statistics watch

1. How did other find the exam? It wasn't too bad... BUT WE'VE FINISHED!!!
2. yep I thought it was mostly ok, only i got stuck on a few eg. the David's Mean one and also the very last question..but hopefully itll be ok...

it feels so wierd to be actually DONE, no more revision, no more exams heehee!!!
3. i got 108.33333 for the last question...??

i got 108.33333 for the last question...??
not me, i just guessed so you'll probably be right. i didnt know what method to use, so..
5. Yea - The how many fish in the pond with tags stumped me!
6. for that i guessed 314

it must be wrong i was destroyed for 2 and a half hours
7. what did ppl get 4 that crude and standardided thing!?
8. i got 100 for the last question
9. i got twothousand and something...i think 2183 or something similar (for the tagged fish question)
10. did u get 2 for the blackcueernt drink vs the apple !!!!!!!!!!!!???????????
11. i said blackcurrant i used the standardized score thingy (value-mean)/std. dev.
12. For the last question I think it was 110...
13. i put apple for the apple/blackcurrant machines...
14. wat was the last question i forgot?
15. how the hell did u manage to do the last question?i put more than 150ml, because the mean of 100 with standard deviation of 10 could have a maximum value of 150, so I said it should be more than 150.
tell me how did u do that?
16. i thought that was quite hard!got 100 and something(109 or 106 or maybe it was 110!) for the last question. i said apple as i ended up with 1.4 after doing an equation, which was less than the 2 i got for blackcurrant and so apple was then the closest to the mean. does that sound wrong r what!!!!!!!!for the tagging thing i got 2ooo and something as well.4 the crude and standardised thing i got two numbers that were 200 and something.i just left out the david mean thing, what was it???3 marks????thought i could afford myself that but lookin back i ain't so sure!!!for the number of pupils out of 390 who were good at spanish and french wat did u all get? i got 312 :-(
sorry 2 any1 who hates goin over exams afterwards but its the only thing that puts my mind at ease!:-)
17. Didn't get the last question, just took a random guess, but the rest was ok. Think i got around 2142 for the fish thing but can't really remember...... fnished working for 10 weeks now! Yay! (stats wasn't the best way to end it tho....)
18. ????out of 390 who r good at spanish and french?was it kinda the last question on this probability, where it asked if 390 are good at spanish, how many in overall are good in french. I got something like 433.lol.

i think that wen u got 433 u multiplied it by 0.8 to get the answer, nt sure tho
20. Dammit- just realised that i got the standardised scores thing wrong because i'm incapable of dividing 4 by 2- i put 0.5! think i got 243 for the David's mean thing cos i thought that since it was between 225 and 255 u just needed to find 0.6 times 30 (the differnce) and add it onto 225 (which represented three....not sure if that's right tho....lost out on my A* there!
