GCSE maths statistics coursework - please helpWatch
leave da poor girl alone man shes only looking for a bit of help the sma as everyone else if ur teacher cant help u hes a prick but u can ask him for guides on the coursework hes aloud to give u that and if he still dusnt help smack im
well YOUR not going to pass the english exam.
mode is da nos that occurs most
median is the middle number
hope it helps
I am top in the skool tho!
I cant seem to put it together tho!
I just have pages and pages of graphs an charts in no order!
Oh an I missed the deadline 2 weeks ago!
U need help! I need a miracle!
my hypothesis is the value of a second hand car will decrease as it gets older (using saloon cars only). i'm looking at how steeply the price will drop as well. I've done a cumulative frequency graph, box and whisker diagrams, mean, quartiles, tallys and scattergraphs BUT HOW CAN I INCREASE MY MARK? I HAVE NO IDEA HOW TO REPRESENT DATA!!
I don't understand maths even though i'm predicted a B.
help would be appreciated! thanx! whats statistical diversity?
Anyway, i s'pose I should get back to it, eh?
I might come back here if I get stuck. <_<
I am really really stuck with my GCSE maths coursework and i was wandering if anyone could give me any tips etc as i dont find my maths teacher any help what so ever!
My hypothesis is: The further you travel to school, the longer it takes.
I have written a reasonable amount plannning however any tips would be appreciated as i really need to get a top grade to be able to go to the school i want to go to and study math a-level.
I have collected all the sample, explained about it etc. and have drawn a histogarm (not yet explained it) and computer generated a scatter graph with the correlation coefficient in it (which i need to further explain - i need to fully understand the correlation coefficient to do this)
I have also been told about standard deviation - however i dont know if this is relevant to my question.
Also do i need to include very simple stuff such as mode, median, mean etc???
Sorry about the length of this but i thought i might as well include as much info as possible.
and btw to do a stratified sample you do:
total number in category (e.g. number of year 7 boys )
________________________________ _________ (as in 'divided by')
totla number of all the boys and girls in all the year you're using in your sample
then MULTIPLY that answer by the total number of people you wnat in your sample. If you're using all five year, year 7-11 then you should use about 150 ppl in ur sample. alrite?
That is one place to get your revision guides from, ask your school if they do them because mine does and its very helpful. Shops like WHSmiths also do alot of revision guides.
Standard deviation is worked out using the formula below. Ive also used an example to demonstrate (if the picture works) which was taken from a worksheet I've done before, so you might recognise it. Hope you can read my writing.
Thanks to Phil Cluff for lending me his webspace. Check his site if you want.
There are many different ways of working out standard deviation, thats the one I use. Try and work out rural to see if you get it. By the way I do not garantee that this is right (just so you can't tell me I said it was and i was wrong). I don't really get this myself completely if I'm honest (its been like a year since I last did this), so anyone who does and knows I'm wrong please warn me.
I start my standard deviation maths coursework in just under a month. I'm doing this coursework on football and if anyone has a copy of the sheet and they could scan it in and send me it i'd be very grateful. We had a lesson on it today, expect my friend missed it and she could benefit from taking a look at it. Thanks to anyone who can do so.
thats the link, cos I dont think it worked
your going to fail Hannah
Don't worry Hannah, you'll be alright!
