PLEASE HELP. Medals. Question in comments. The table below shows the number of students from different classes of two schools who participated in a sports competition: School A| 25 21 2 22 20 21 20 23 1 School B| 3 2 1 5 4 2 3 4 3

How can you use box plots to compare the median and interquartile range of the data?

OpenStudy (aripotta):

if you already had the box plots made, then the longer the box, the bigger the range. and the more to the right the median is, the bigger it is

School B:

Thanks. I think I understand what to answer now. :)

OpenStudy (aripotta):

well you'd want the box plots to be on the same number line, that way they're easier to compare. and $$\Large \boldsymbol{ \rlap{\color{#008AFF}{\hspace{2.5pt}n}\color{#0073FF}{\hspace{0.34pt}o} \hspace{3pt}\color{#005CFF}{p} \color{#0045FF}{\hspace{0.9pt}r} \color{#0017FF}{o} \color{#0200FF}{\hspace{1.7pt}b} \color{#3000FF}{\hspace{1.5pt}l} \color{#4700FF}{\hspace{0.4pt}e} \color{#7500FF}{\hspace{0.9pt}m} \color{#8C00FF}{\hspace{0.5pt}o}~\LARGE\color{#D100FF}{\ddot\smile}}{\hspace{1.5pt} no~p\hspace{0.3pt}r\hspace{0.4pt}o\hspace{1pt}b\hspace{1.5pt}l\hspace{0.4pt}e\hspace{0.4pt}m\hspace{0.4pt}o}}$$

So school B has a larger interquartial range and school A has a bigger mean.

OpenStudy (aripotta):

yes

OpenStudy (secret-ninja):

Thanks. ^-^

OpenStudy (aripotta):

wait

OpenStudy (aripotta):

school a has a bigger interquartile range

OpenStudy (aripotta):

and bigger median

OpenStudy (secret-ninja):

Oh okay.

OpenStudy (secret-ninja):

Thank you.
