what is quartile 1 of these numbers: 4,8,8,3,6,4,4,3,6,7,6

what is quartile 1 of these numbers: 4,8,8,3,6,4,4,3,6,7,6

first you sort them

3,3,4,4,4,6,6,6,7,8,8

then find the median which would be 6

then look at the sequence less than the median

3,3,4,4,4

and find it's median which would be 4.

and so 4 is the lower quartile or quartile 1

  4,8,8,3,6,4,4,3,6,7,6
