Hi everyone,

I understand that postcode is a categorical variable, however, is it nominal or ordinal? Can you please explain why?

Thanks!

I think postcodes are ordinal as you can put them in order e.g. 3000, 3001, 3002 etc

Hi guys,

How would I go about working out the following question?

1. The ovens and other equipment in Phillip's kitchen have been depreciated using a flat-rate depreciation method. A recurrence relation that models the value of the kitchen equipment after n years, Vn, is shown below.
Vo = 5800, Vn+1=Vn-350
a. What was the original purchase price of the kitchen equipment?


Thanks

Vo means the starting point/original purchase price

How many marks can you afford to lose in both further math exams in order to score an A or an A plus :p?

Hi Jayleno,

This varies from year to year depending on the difficulty of the exams and hence, how everyone performs.

However, to get an indication, you might want to take a look at the graded distribution for Further Maths. This is on the VCAA website.

Hope this helped!

Not sure if this was unintentionally unanswered but for a major segment, you're better off doing this.

Area of major segment
= Area of entire circle - Area of minor segment

Hi guys,
I was just wondering, when comparing parallel box plots, what would it imply if there was a statement saying "the test scores in Box plot A, on average were higher, than the Box plot B"

Hi guys,

"the median of Box plot A is higher than the median of Box plot B"

"the median of Box plot A is higher than the median of Box plot B"

Alright, but is the median the only factor you could discuss. I understand it is the main one though.
Thanks

In this question, yeh. If it just said to compare the box plot you could talk about IQR, range, outliers and so on. But when asked about one thing like the median, it's best to just talk about that thing so you don't start waffling.

A box plot gives you information on the min, lower quartile, median, upper quartile and max. You can infer range and IQR by extension.

It doesn't show anything about the mean or standard deviation explicitly.
