--- Quote from: sleepeatrepeat on October 28, 2021, 12:55:49 pm ---There are 9 numbers between 3 and 7 (4, 4, 4, 4, 5, 5, 5, 6, 6)
9 / 25 x 100 = 36%

deseasonalised temp = 23.71 + 0.457 x month
= 23.71 + 0.457 x 13
= 29.651

predicted temp = 29.651 x 1.13
= 33.5 degrees
= 34 degrees

Hope that helps... ;D

Hey,
I'm just wondering how you got the seasonal index of 1.13?

Thanks :)

sleepeatrepeat:
The 1.13 comes from Oct 2017 coz if oct 2017 is taken from the table and oct 2018 is added...they all need to have an average of 1 which means that the next month (Oct 2018) will have the same as the first month (Oct 2017)...

Sorry don't know how much of that makes sense... ??? :o

Hi,

Does anyone have access to the VCAA 2005 and older VCAA exams?

On the VCAA page there are exams only up to 2006.

Thank you.
