Just ignore this particular question.
As long as you know how to differentiate () between the two different types of variables, then it doesn't really matter.
(I use the differentiate in normal English way too much )

number of tourists is the independent and the other is dependent. But my teacher says otherwise.. hrm

yeah that's correct.

matty- the exchange rate does not directly affect the tourists behaviour, they go when they please and themselves affect the exchanges, not the other way roundddddddd :p

But doesn't the exchange rate affect whether/where they want to travel or not?
Particularly if it makes costs cheaper/more expensive?

I was doing independant and dependant variables today. I was like wtf. It said identify the dependant variable and I got every single question wrong. So I said I misread the question and put independant variables at the top. I think I know how to do it now...

LOL, independents do not change in relation to anything else (they DON'T DEPEND on anything)
Dependent variables change according to other variables (they DEPEND on something else)

Hope this helps!

This question is a dud, they are interdependent. But I think the.watchman has the more appropriate approach, tourist numbers are more dependent on exchange rate than the exchange rate is dependent on them.

don't stress about homo questions like that.  the exam will either give you good questions where one variable is clearly independent and the other dependent, or they will tell you which one is the independent variable.

question 9 core was nice kinda trick they played last year with independent variables:
