Question

find the inter quartile range and median for 21,3,4,86,43,55

Answer 1

on arranging the given data:

3,4,21,43,55 and 86

thus,median=(21+43)/2

=32

the upper quartile=3n/4 th term

=55+86/2

=141/2

=70.5

and the lower quartile =n/4 th term

=3+4/2

=7/2

=3.5

thus,inter quartile =70.5-3.5

=67
