I'm not sure how to do this i was not there that day they taught this and idk what some are and it was yesterday so..

Ok so minimum is the lowest number 30
lower quartile is like the every fourth number 51
median is the middle number 43
upper quartile is 36
maximum is the biggest number 57
the interquartile range is found by doing upper quartile minus lower quartile which equals 15

hope this helps. :)
