I dont understand Seasonal Variations...........

Im doing June 06 paper 1.2, and a bit confused. How What Why???

How did they get 6%?? And what does it show exactly?

Can someone show me the light at the end of the tunnel?? :001_smile:

ah i got caught with this one too

its the q4 fig divided by q1's figure gives 1.06 = 6%

when you look at the original sales volume and do the calculation for those figure you get 0.87 i think

0.87 + 0.13 = 1.00

hope that helps

also i have a calculation for it i just remembered from college
additive model - gives figure in £ form

y = t + s

and the proportionate model - gives figs in % form

y = t x s


in this case y = sales volume
s = seasonality
t = trend or the seasonally adjusted fig
