wait so having a spiral book is not allowed? and if you cut out the pockets so that there are no pockets for dettached sheets to be in is that allowed?

I think its the fact that you can very easily rip out a paper.

Spiral books aren't allowed?!
 what about ones without pockets...

[BLACKCATT]

I've spent a lot of time on my bound reference, i really don't want to start again...

[yazza]

same.... so can someone confirm?
i have a spiral 5 subject book but have ripped out the pockets so that there are no pockets.
thanks

Regarding the spiral bound, make sure it is permanently bound and doesn't have perforated lines so it can easily be ripped out. I would put tape on the bound to be 100% sure.

On 2005 exam 2, there's been a question where you were required to actually describe how a data transformation linearised the data. Could someone check whether my expression in regards to how data can be linearised is accurate.

Thanks

x² transformation: stretches large x values closer towards the horizontal axis relative to smaller x values.

log(x) transformation: compresses large x values closer towards the vertical axis, relative to smaller x values.

1/x transformation: x values are reversed and compressed towards the x axis.

y² transformation: stretches larger y values closer towards the vertical axis.

log(y) transformation: the points closer towards the vertical axis need to be compressed more towards the horizontal line to linearise the data.

1/y transformation: the points are reversed, and y values closer to the y-axis are compressed towards the vertical axis, to linearise the data.

Could someone please check these ^^ for accuracy in expression! Thanks
