I have question. Anybody willing to take me through step by step?

OpenStudy (eyust707):

I can

OpenStudy (anonymous):

depends upon what is the question. :/

OpenStudy (eyust707):

... probably =P

OpenStudy (eyust707):

First rewrite the numbers in order form least to greatest. Ill let you do this part.

OpenStudy (timaashorty):

11, 13, 16, 18, 21, 23, 24, 29

OpenStudy (timaashorty):

& then ?

OpenStudy (eyust707):

We need to find the median

OpenStudy (timaashorty):

21 - 18 ?

OpenStudy (eyust707):

The median is the number wich is in the exact middle of the data

OpenStudy (eyust707):

The average between 21 and 18

OpenStudy (timaashorty):

there isn't one, so i subract the two middle numbers instead?

OpenStudy (eyust707):

|dw:1395263833709:dw|

OpenStudy (eyust707):

Take the average of the two middle numbers

OpenStudy (timaashorty):

OH 39/2 = 19.5 ?

OpenStudy (eyust707):

correct. remember that number it will be the very center of our box and whisker plot

OpenStudy (timaashorty):

Thanks :), now whats next?

OpenStudy (eyust707):

Find the median of the numbers on the left half of the data and find the median of the numbers on the right half.

OpenStudy (timaashorty):

11, 13, 16, 18, 13+16/2 = 14.5

OpenStudy (eyust707):

correct

OpenStudy (timaashorty):

21, 23, 24, 29 24+23/ 2 = 23.5

OpenStudy (eyust707):

correct

OpenStudy (eyust707):

The last values of importance are the min and max values. (these become the whiskers)

OpenStudy (eyust707):

11 and 29

OpenStudy (eyust707):

Now just plot above a number line

OpenStudy (timaashorty):

so it's 11 14.5 19.5 23. 5 29 I plot those numbers^?

OpenStudy (eyust707):

yep

OpenStudy (timaashorty):

OpenStudy (eyust707):

OpenStudy (timaashorty):
