when we do the whisker plot does it really matter that we have to start from 10 ??
no, depends on the data set. whisker goes from lower extreme to lower quartile & from upper extreme to upper quartile...
Find the median , the first quartile ( Q1) and the third Quartile ( Q3) 145,159,162,163,165,173,174,177,177,181,184,186,193
help me
what number(s) is to the right of 186? can't read it...
193
:( are you able to help me?
145 = lower extreme, 193 = upper extreme. 174 = median, are there any numbers after 193?
No !
ok, your quartile values are 25% below average & 25% above average...sorry don't have my calculator with me & i'm having trouble doing this in my head...
what?? i got the different answer :/
how? what did you get?
For Q1 i collect first half of the numbers and the look for median
and for Q2 you collect rest of the half numbers and then do the samething, find the median
yep, you're right, i'm sorry, you're abs right...
and????
some texts exclude the median when finding the lower/upper quartiles when you have an even number of data above & belowe the median & some include it...not sure which method you're being taught...
in your problem, you have six values above & belowe the median...so if you use method of inclusion--you include the median...if you use method of exclusion you get a slightly diff answer...
am i rong?
no, you are correct...if you include the median...then q1=163, and q2=181...
and i think method of inclusion is most popular & taught most often...
make sense?
i think im right
i think im right
yes, you're right.
:) Yaayyy can u help me with the display data : whisker plot ?? like do i need to start from 10 for those numbers?? or?
haha, sounds like you know more than I do about what you need to do...i haven't actually taken a stats class yet (want to though), so i only know what i've picked up from engineering classes mainly.
Oh you took all calculus classes ha?? this is what i dont lik it.. whenever i used to com here for help.. noday knowss about that stats :/
hey, i tried... plus, it sounds like you know more than what you give yourself credit for...
Man i dont know anything and i got test tomrw :(
