no, depends on the data set. whisker goes from lower extreme to lower quartile & from upper extreme to upper quartile...

  • anonymous
:( are you able to help me?
anonymous
  • anonymous
145 = lower extreme, 193 = upper extreme. 174 = median, are there any numbers after 193?
anonymous
  • anonymous
No !
anonymous
  • anonymous
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...
anonymous
  • anonymous
what?? i got the different answer :/
anonymous
  • anonymous
how? what did you get?
anonymous
  • anonymous
For Q1 i collect first half of the numbers and the look for median
anonymous
  • anonymous
and for Q2 you collect rest of the half numbers and then do the samething, find the median
anonymous
  • anonymous
yep, you're right, i'm sorry, you're abs right...
anonymous
  • anonymous
and????
anonymous
  • anonymous
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...
anonymous
  • anonymous
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...
anonymous
  • anonymous
am i rong?
anonymous
  • anonymous
no, you are correct...if you include the median...then q1=163, and q2=181...
anonymous
  • anonymous
and i think method of inclusion is most popular & taught most often...
anonymous
  • anonymous
make sense?

i think im right
