If Q2 = D5 = Median
Which means if the 2nd quartile equals to 5th decile and also the median.. then how do we find out the fourth decile?
I mean is there a way to find it out through this?
Then what is D4 going to be?
I am talking about Deciles here..

Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportion (.4000) and its Z score. Of course, since it is below the mean, it will be negative.
