If Q2=Q3, can we draw the box plot of data?

Answer 1

So the median is the same as the 75th percentile...

so the data looks like this:

x1,x2,x3,....x0.25,.... Xm-1, m,m,m,m,......m, m=x0.75, ....xN-1, Xn

where m = median = Q2 = Q3 = Q75%

GO ahead and stack Q2 and Q3 labels on top of each other
