hey guys i was just wondering whether any of u know what "assignment 1,2 & 3" are? coz ive just written their due date down in my diary and then thought "wait, what the hell are they?"

we havent been told about them in the lecture have we?i wouldnt be surprised if i missed it that woman was so boring! lol

 

[iambored]

no not in the lecture. it might say in the course outline? i remember reading that (either 1 or all 3, i couldn't understand) were group projects, with 3 people in the group. i read that in the course outline they handed out. i dont know if it had the exact assignment

 

[jlh]

did you look in the stat170 lecture notes?
or you might get the assignments later on in your tutes!!

for the tute homework this week what do they want us to say about each study?

 

[iambored]

i havent read the tute h/w so i don't know

but i have a q too. for gnats and wasps - each gnat is worth 1 mark, and each wasp 1/2 a mark. (i am guessing it's 1% and 1/2% respectively for our final grades)

take the gnat for example. if you get 100% = 1 mark
what if you get 50% right - will you get 1/2 a mark (so 1/ 2 a percent in your grades) or nothing?!

ul prolly get your group assignments in your lectures.

yeh that sounds about right


dont worry about the assignments, they are easy, same for gnats and wasps.

A tip for the final exam... just do lots of past papers, the structure and question formats are the same , so if you can do all the past papers then you'll ace the exam.

 

[iambored]

cool, i like exams like that, like the SC, past papers helped a lot

do they give us copies of past papers?

and so if we don't get 100% in each gnat/wasp, we still get SOMETHING in our final mark. we don't have to get 100% each time? i'm thinking you meant that sounded about right, and not that the 'nothing' part sounded right.

thanks for that for a good cause

Yeh the past papers should be available online to print out.

You dont have to get 100% each time, but getting 100% means you will get max marks for gnats and wasps

i got 84 or 87% in my first one

not happy!!

it depends on your calculator

but find the button which has "" and thr curly x on it. x means standard deviation.

curly x with the line on top means mean

The ones above, that is Shift 2 works for my Casio Calculator, but i think it would depend on the brand.

 

[Grizzly]

yea, on my sharp calculator (non-text recalling or whatever its called ), in stat mode, after entering all the numbers, just press 1 button to get SD, Mean, and median i think....was hoping it does whiskers/fences for me, duno yet ..buts its easy enuf....

 

[iambored]

whiskers and fences? some calculators do that? that would be cool, i have to try and see if mine can do that

 

[Grizzly]

some calculators do the exam for you.
