What is the seasonal index for the Third Quarter?

Okay that makes much more sense. When you look at the graph, between year there is 4 seperate numbers of employees for each quarter of the year. If you look from the start of 2005, for example, there are four data points: 46, 30, 20 and 14. This would be looked at like so:
  • Q1(2005) = 46 employees
  • Q2(2005) = 30 employees
  • Q3(2005) = 20 employees
  • Q4(2005) = 14 employees

That's all good and simple, however we need to keep in mind the position that there quarters are falling. If we are predicting them we would not insert (1) (2) (3) and (4) as quarter numbers unless we are predicting for 2004.
It varies from each year, so on the x-axis, 2005's quarters would fall on [5] [6] [7] and [8]when predicting.

Now from the graph you have to direct your eyes to 2012. I must point out there is an error on the graph, after 2010 it should say 2011!! (bad writers!)
So i see where your confusion arises, it looks like 2012 begins on point 29, and even if that was wrong (supposed to be 2011) it would start at 34, making the 3rd quarter either 32 or 37.

If the answer is 34 it makes zero logical sense. Which exam was this?

Unless of course you split 2012 in 8 different segments, leaving 2 segments per quarter I guess.
  • 29 and 30 = Q1
  • 31 and 32 = Q2
  • 33 and 34 = Q3
  • 35 and 36 = Q4

But even then you can't determine which quarter 3 would fall on.

Bad question. They must have also left out a point for 2004, because there are only three data values.

I'd say that data point lies above the highest y value on the y-axis. It should be there though. Terrible question.

That doesn't make sense - who would create a graph which doesn't fit all the data values in? :P

I'm not surprised - Kilbaha not only have ridiculously hard questions, but both their exams and their solutions are plagued with errors. Steer clear of them!

Kilbaha obviously :p

Yeah they are pretty terrible sometimes. This question is just so ridiculously wrong. Having two data points for 2012, and then continuing to say that the third quarter is at point 34 makes absolutely no sense. And how can you get an accurate prediction without Seasonal Indices?

I had to do this as an official school trial exam today. Facepalm at the paper as a whole, as well as the school for even picking it (they obviously didn't even proof-read it -.-).

Would you happen to have the solutions by any chance? ::)
