okay follow a similar step to what we did like in the question before :)
Arrange your data in ascending order (lowest to highest).
Then count how many numbers there are in total.

xD give me a minute to work it out myself :P
OpenStudy (butterflydreamer):
hmmmm you forgot one part ^_^.
The question is asking for Q3 not Q1.
So you have to look at the upper quartile instead
OpenStudy (butterflydreamer):
so you apply the same thing you did for the lower quartile (Q1) which BTW was 101 so good work there.
But we're trying to find the upper quartile (Q3). Which is the last quartile
OpenStudy (anonymous):
oooh okay
OpenStudy (anonymous):
im lost haha
