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

    145 = lower extreme, 193 = upper extreme. 174 = median, are there any numbers after 193?

    and for Q2 you collect rest of the half numbers and then do the samething, find the median

    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...

    no, you are correct...if you include the median...then q1=163, and q2=181...
