Question

Please help!!! Make a box ­and ­whisker plot of the data.  24,18,29,21, 16,23,13,11 

Answer 1

Median = (18+21)/2 = 19.5
IQ1 = (11+13+16+18)/4 = 14.5
IQ3 = (21+23+24+29)/4 = 24.25
so answer is first one 
A. 

Answer 2

11,13,16,18,21,23,24,29
minimum = 11
Q1 = (16 + 13)/2 = 29/2 = 14.5 ....this is where the box starts
Q2 (median) = (18 + 21)/2 = 39/2 = 19.5.. line in the middle of box
Q3 = (23 + 24)/2 = 47/2 = 23.5 ...this is where the box ends
maximum = 29

Its gonna be graph B
