I don’t think that’s how that works. Since there’s no value you just average the 8th and 9th value, that’s how medians work. i made box plots for C and D, and D is different. I already said that the five number summaries are all the same except for D, how can that be argued against when it directly affects the box plot?View attachment 45240View attachment 45241

NESA making us invest so much time for 1 mcq smh

UPDATE! I underestimated my ability to recall information for modern…i have no idea if I was just absolutely having a BRAIN BLAST during trials, because I did a lot less study but finished all the questions on the paper no worries. Man.

I have been humbled. Stalin, you grey blur you…

I did not get to apartheid IM SORRY APARTHEID!!

clearly, I'm expecting my band 6 in the mail

Being so loud and wrong is hilarious.

The life of a troll

yes, the average of the 8th and 9th value is 8.5. therefore the median is in the 8.5th place for all graphs. using this logic you can figure out the median for A,B,D which is in the middle column and is symmetrical(like the box plot). but if this is used for C, then the median would be 0 because the 8.5th place is nothing. which is wrong

once again, that’s not how that works. you just skip to the next data point. the same idea goes for a stem and leaf plot, just because theres values in the 10s place and values in the 30s place and no values in the 20s place doesn’t mean the median is 0. i don’t think you understand how this graph works.

Yes...you skip to the next data point. then there are 7 values to the right and 8 to the left of the median. that means that the data is no longer symmetrical. that means that it cannot be matched with a symmetrical box plot. that means I don't think you understand how this graph works

year 11 went really fast but year 12 has felt pretty slow

Both went quick fr

no? i will represent the median with a line: 1 1 2 2 2 2 3 3 | 5 5 6 6 6 6 7 7. you see how there are 8 values on either side?

this is stuff you learn in year 7 or something i’m not even trying to be rude

hahah these little jabs are just gonna make you feel like more stupid when you realise why it's C. HISTOGRAM = frequency of something. you've just assumed that the x axis is numbers when it may not be. it could be absolutely anything. e.g. if your "4" actually represents "amount of people in denial about question 15", then how can it be the median if no one is? (theoretical though because clearly someone is). on a histogram you can't make something that literally does not exist the median

 

[bcv]

we are still debating this histogram question

I hope it is C because I guessed C

 

[spiderfan44]

yo i dont do m ath but based on vibes i think c

 

[ihatehsc24]

same but looking at katie's and other solutions, all of them say D :/
plus I think katie got a valid reasoning

i shall defend my intellectual honour to the end

yes, i know that it represents frequency. regardless, the result is the same. D is different than the other options. plus, the advanced solutions also agreed that D was the answer - tbh i trust that. you cant have a median of 0 if there are data values before and after it that are above 0. its the exact same thing with a stem and leaf plot like i said. im sorry. that’s just not how medians work. if you give me another reason that is plausible i might change my mind.

 

[sainzsgf]

i cant wait to see what nesa puts as the answer to this question and we can finally settle this debate (praying to god its c )

 

[lyingsalsa]

yo why is there so much smoke outside

mb, had a couple of ciggies for lunch

As much as it hurts for me to say, you should ignore those who say its c because they seem to be trolling and forget how median works...I forgot why I selected c but I agree the answer's d now
