My class is half way through the core SAC, we should be starting our next module (Number Patterns) at the end of next week. I think we are pretty slow? Where is everyone else up to?
-
Well i think our school is pretty behind. We start our core SAC in 2 weeks! So consider yourself lucky :)

Wow.. will your SAC have chapter 4 in it? Mine doesn't, but we still covered chapter 4 (very quickly though).. maybe thats why your behind me.
-
my core sac is tomorrow dear god it is going to be boring
-
im doing mine now ive done 2 periods on it, yay only 8 more to go. Pretty easy so far but very time consuming
-
Our core sac is next week- it goes for 7 periods
Is anyone else's sac that long?

Yeah, mine is 10 periods (40 minutes is a period). It seems long but time is starting to get tight. The summary at the end will need the longest amount of time, my teacher said to leave 2 periods for that.
-
Mine is 7 periods (50 minute periods). Only used one period so far. Fairly simple but very time consuming drawing three boxplots.
Ok... not that time consuming but still not as quick as I usually would answer questions
-
i fail 2 scale all
all the work i hand in for correction has
SCALE! SCALE! WHERE IS SCALE?

I'm confused?? lol What are you saying?

Do you mean on box plots? Me confused.
Um anyway their was a bit of a =S on our sac. It said draw all three boxplots on one set of axis's but if you did that it would be too squishy because the data was spread out. (0.55 to like 12.57) so teacher said it would be fine if we did three separate box plots on 3 axis's but we had to keep the same scale. Does that mean that for each boxplot in my examples I had to keep the increase in the X-axis constant? Like each cm was a 0.5 tons per capita increase. It stayed the same on all of them and I also did a little scale . 1cm = 0.5 tons per capita
-
its almost on all of the graphs and boxplots

I think you need to keep the 1cm = 0.5 tons per capita, but you can change the start and end values of the scale? Like start the scale from the boxplots minimum value and go to the max value.. as long as you keep the 1cm increase.
I have a question also:
'Determine the equation for the three median regression line. Define and use appropriate symbols'.
What does 'Define and use appropriate symbols' mean? Is it just y=ax+b.. asking me to put the appropriate values in the right spot? It made me a little confused as to what it was asking.
-
Yeah defining the appropriate symbols does mean providing the equation in the form of y=ax+b.
But it also means that you have to define the two variables in the relationship.
That is, what do x and y symbolise? I am unaware of what the question entails but an example of the two variables might be height and weight.
-
Yeah, okay I thought that was it. Thanks for replying Nick. The variables are GDP and literacy rate. So it is simply a matter of just stating, x=GDP and y=literacy rates ?
-
Thats okay.
You may also need to state what "a" and "b" stand for.
That is,
m = gradient (how steep the line is)
b = the Y Intercept
Given that it is an interpretation question, they probably expect you to demonstrate that you understand what all elements of the equation mean.
-
Yeah, i'll make sure to demonstrate my knowledge through what you said. Thank you for helping.

No we havent done Chapter 4.
Ours is on the Computer, but im not too keen on how to go about it. Does anyone know what it covers specifically from Chapters 1, 2 and 3?

My SAC is mainly just about Box Plots, Scatterplots and a few other things (mainly chapters 2+3). I then need summarise everything I have done and produce a full analysis. The conlcusion at the end of my SAC is the most important thing because it shows that you are cabable of doing the work and know how to analyse and relate it back to the theme 'Globablisation Issues'.

Our SAC is supposed to be about Globalisation too. I suppose it's quite a trendy topic.
I can't believe your SAC is on so little! We have to cover everything from Chap 1-6 blehhhh

lol I was exaggerating a little.. but I can't really think what else is in mine.. and apparently VCAA provides the theme every year?

lol I had no idea the VCAA provides the theme. Why would they have to do that?

My maths co-ord told me that VCAA provides the theme every year. I don't know why though.

When our school did the Core SAC last year, we certainly didn't have a theme provided by VCAA. Our SAC was something about motorbike licensing over a period of time and the trends that occurred each year. It had obviously been used for quite a number of years because it had "2004" written at the top of it.
VCAA never dictates to schools in regard to the "themes" of SACs. It is at the school's discretion to decide.

Well, I have no idea then.. maybe they provide a number of themes or suggestions that the school may choose? But yeah like I said my co-ord said the theme was provided by VCAA.
-
I would say that your teacher purchased some kind of support resource from VCAA. It might have provided guidelines/examples for possible SACs.

I had my SAC today. Basically the teachers are testing me on Chapters 1-7 (Scatterplots, Boxplots etc.) We have 8x45mins sessions to do it. I think i'll have time, i hope..
