Sketch a pdf based on the whisker plot, you see how it's negatively skewed. negatively skewed the longer side is on the left

ooohh okayy thanks!!

genuinely how hard would it be to get a 50 raw tomorrow if I haven't studied much?

not even hard, u can probably do it just with basic formula sheet skills

 

[ALolly]

isnt garden a positively skewed?? or am i tweaking

Basically if there are more scores less than the median then its negatively skewed and vice versa. I also thought it was positive at first glance but always look at how many scores are above or below the median

Ya'll reckon tmrs paper will align with 2023 difficulty?

 

[melanie_o]

Yes please

 

[Clai]

please that or 2024 ill be happy. if its like 2021... therell go my b6

 

[ALolly]

whatever it is i just hope its good

 

[bigupsanky]

nah the paper will be good trust the process

guys for skewness of box and whisker plots is it only considered negatively skewed if the median line is towards the right of the box? what if the line is in the centre of the box but the left "whisker" is longer than the right?

whiskers determine the skewness. so if one whisker is longer than the other then its skewed that way. also, do u guys reckon we need to know arithmetico-geometric series (yes im hearing this term for the first time in my life too) like this one? i found this in atar notes

thanks.

hopefully we don't cause i've never seen that before and theres no time to learn it.

its something to do with geometric progression i always get that wrong

isn't that when an AP and Gp is combined like in the question the AP series is 1+2+3+4... and GP is 1/6 + 1/6 ^2 ....
I've only seen these questions in like harder school trial papers otherwise they aren't that common

a quick google showed me the formula it looks relatively simple?

hmm ye i saw the working out u need to think outside the box for it lol

I saw one in jr 2025 I think and was defo confused

How difficult do we think this yrs paper going to be? For adv?

it will be fine...

right?
