Quick Question- When applying a log transformation to linearise the data, do we you natural log or log base 10?
base 10, it should be the default on the TI if you leave the field blank.  :)

What's the consensus on mean vs. median? Doing a check on my bound reference and it's not there.

Is it just outliers/skew = median, symmetric/no outliers = mean?

Yeah no extreme values/outliers and skew means you should use mean

And for extreme values/outliers and skew you should use median.

I'm taking a protractor and ruler into the exam as a final resort (bearings questions). I struggled to do VCAA 2013 Geo & Trig Q8, and I got the right answer by double checking with a calculated sketch.

We can bring in a protractor? I swear bearings will be the last thing I see  ::)

From the VCE exams navigator booklet:
"Basic stationery items do not include...or geometrical drawing instruments such as compasses, set squares, and protractors."

What's the difference between a cyclic variation graph and a seasonal variation graph? I swear they look the same

Cyclic is repetition over longer periods of time;

You'll see seasonal more than once a year (usually)

You'll see cyclic every year or couple of years
