Grouped frequency table?

[IzzyO]

Hello, Everyone,

I'd love to know if the nSpire can create grouped frequency tables.
I'm particularly interested in finding out if the the calculator can
interpolate the median and quartiles from grouped frequency data.

Any and all help will be gratefully received :-)

Have a look at the example that starts on p18 of this booklet:

http://education.ti.com/sites/UK/downloads/pdf/IB_Booklet_web.pdf

 

It uses discrete data, but you could easily adapt it to continous by just using the midpoint of each interval in place of the values...

 

Cheers

Andy
