Did you find Exam 2 easy or hard?

[lachymm]

Yeah median is 15.5

[xXNovaxX]

thanks guys

In the question in core...It says something like "Explain the pattern of the 3 median smoothed line" What did you guys write, i wrote something like Between February and April increases largely then between April and November remains consistent?

This is the only question i feel "iffy" about

did you get like a straight line from 1/4 way through? like it remained _________, and only icnreased in the first 2-3 months?

[Ilovemathsmeth]

I got 93.6% and left it as that because they didn't specify the number of decimal places (for the volume one).

I wrote the exact same, but im not 100% sure if they were asking that.

[lachymm]

Yeah man sure did, 3 median smoothing gave me that time series plot also

What were the grades for exam 2 like last year?
eg. what score range constituted an A+, A, etc?
Cheers.

If i get 54-55+ I'll be happy.

[Ilovemathsmeth]

I had about 15 minutes to check, but I found the matrices section quite complicated (towards the end).

[lachymm]

Anyone else remember any questions from core, graphs, business and networks i wanna discuss em

[Fireworks]

thanks guys

Me too. I wrote at the top |----trend one----||-----------trend two-----------|
Then wrote something like yours. I hope that the ambiguity of that question doesn't means
that I lose a mark.

[lachymm]

The r value (pearsons correlation coeeficient) is negative... Not positive

Yea i had 15 mins spare.
Again Business was a joke, way to easy, trig was straight forward and number patterns was also straight forward however it needed a little thinking.

[lachymm]

Also i think for 4c the correct answer isnt "above average" but on average the season of summer is 5% above the average for all seasons

[tho0015]

so annoyed at my mistakes right now...like not making pearsons negative grrr
