#

44 is the upper quartile as shown by the box plot

#

so find the upper quartile of 3000. Then subtract that from 3000

#

Can u explain how to do it as i have not done it before @brisk shoal

brisk shoal
#

You haven’t done box plots?

#

Or upper quartiles

fast jolt
#

I have but not these kind of questions

brisk shoal
#

so what can a box plot tell me

#

what do each of the lines represent

#

@fast jolt

fast jolt
#

Lowest value lower quartile median upper q highest value

brisk shoal
#

right

#

So let’s draw a line from 44

#

ah wait, our line from 44 is also the line representing the UQ!

fast jolt
#

Yes

brisk shoal
#

so

#

People who waited more than 44 minutes, is also the UQ of 3000. Subtracted from 3000

#

so calculate UQ of 3000

#

but that is also just the LQ of 3000

#

so you can choose which ever one you are most comfortable with

fast jolt
#

Wait so how do I calculate the uq

#

I’m so lost

brisk shoal
#

have you not learnt how to calculate UQ

fast jolt
#

No
