[surya17]

can z1 also be the number of standard deviations below the mean?

[ExamSolutions]

Yes z1 or any z value measures the number of standard deviations above or below the mean.

[ssstvd]

its funny how you can teach me something with a prerecorded video in less than 8 minutes, that my teacher failed to do in several days.

[1h0tsistah]

lol.. when you were saying "naught" i thought you were saying "not".. lol.. silly american over here getting stressed out.. i thought i was getting it then i heard "not".. lol.. silly me.. but thanks a bunch.. i really get it now.. :D

[ExamSolutions]

Pleased to here that. Thanks

[ExamSolutions]

for what calculator?

[mrckb]

someone is at your door at 3:30

[ExamSolutions]

Well spotted!

[mrckb]

that's my problem, when im supposed to be learning i drift and pay attention to other things. but thanks for the help man. are you able to do a vid or give pointers about using the calculator method to find the fi values?

[atanonoyom]

Has any of you worked with SPSS?

[IsThisNoGo]

Yep!! I think you'll find it hard going if you don't have a reasonably good Maths background.You could find more info from Amazon,but suggest you wait till you can do a Uni Course on it.Otherwise you could get a copy of SPSS and google for tutorials,then follow one of them.You'll need a lotta time to fully understand SPSS.

[captainspiwtf]

good man. Nice tutorial.

[madzianott]

yeah my stats exam is tomorrow as well....

From EDEXCEL...

this video is cool

i hope i will get good grade:):):):):):)

[ExamSolutions]

Fantastic. Good luck with your exam.

Have you clicked on Maths Aid?

[yaalovesGod]

[kenzolo]

EXCELLENT VIDEO 5*

[Lionblaze312]

thanks, got my S1 in 7 days and this is really helping! Had my mock exam and only got 22 out of 75!

[ExamSolutions]

Good luck in your exam - glad I could help. I am doing these vids for free in order to raise money for charity. Any donations to OXFAM as a thank you would be really appreciated. Just click on Maths Aid below any video on my site if you want to contribute.

[arefihaseeb]

dont be suprise what u got its normal with stupi statistics, me too i had 28 out of 60.

[xakatski]

dont kno y, but vidoes help more than teachers,

[ExamSolutions]

Hold on - I am a teacher

[xakatski]

i kno, but i learn like this better than, going to class and listening to teachers, maybe its just the teachers at my school dunno, but thses vids certainly help on a scale 10/10

[malashimpi]

God Bless you, i have 10 days till my S1 exam, and this video taught me the normal distribution, where i had no clue how to do it before.

Thanks a lot!

[sams0606]

this is very helpful. this is better than listening to my teacher's explanation.

[otivaeey]

hmm, taking too long for this simple question.

[LidiyaShadow]

thanks for the awesome video, but i have a question, why was the unit for 9 hours squared?

[ExamSolutions]

The two parameters used to define a normal distribution are the mean and variance in that order.

The variance is the standard deviation squared. I could have written 81 but I prefered to leave it as 9 squared.

I hope that answers your question.

[LidiyaShadow]

ohh, i see, thank you for you help. ^w^

[mju6767]

thanks, very clear and helpful

[clanOT]

oh my god this is explained too slow. i dont mind thourough, just not slow.

[Wacko375]

Hey you are now doing statistics also? I think statistics is fine apart from probability and and discrete random variables.

[kingslice75]

Probability and random variables are kind of the idea of statistics. It's like saying math would be great without addition signs. :)

[Wacko375]

Right, I meant they were the topics I didn't get very well. BUT I got an A in statistics anyway =) even though I hate it with a passion. I love core maths.

[lego2918]

Thanks gr8 help!
