# Thread: Quartiles of data

1. ## Quartiles of data

Patient.....A......B.......C.....D.......E......F. .....G......H......I.......J.......K......L
x............160...390...169...175...125...420...1 71...250...210...258...186...243

Find the median, upper and lower quartiles of these data.

I got Q1=172 Q2=198 Q3=254
but the answers I was given say Q1=170 Q2=189 Q3=254

Maybe I did the wrong calculations, but am now confused. Are the answers correct?

The correct answers are Q1 = 170, Q2 = 198, Q3 = 254.
