since the sample size is 11, why did you add one to it to make it 12?

[AfghanGangsta2k9]

[MOHH2COD4]

gr8 vid,thanks,for lower quartile, if theres no middle no i assume its half way?thanks.

[jayemush]

thank you so much! I have a maths exam in 2 days and i completely forgot how to do this..thank you :)

[iiRobyn]

Thank you! Just one question, what do you do if there is no middle number? Like if the middle two numbers are 7 and 8. Do you go half way between the two to get 7.5? Please please please reply :)

[bevets]

Yes! If the 'middle' numbers are 10 and 11 then add then and divide by 2. So the median will be 10.5

[lhamo95]

thank u so much but i have a real test coming up n i have 2 question why do u have to divided by 2 n at the last u said meadian is 2 and lower q is 1 and upper q is 7 then u said interquartile range is 7-1=6 so do u just forget about meadian number 2??

please reply back

[bevets]

The interquartilte range (IQR) = upper quartile - lower quartile.

Here 7-1 = 6.

When finding the IQR you don't need the median.

[lhamo95]

hehe thaNKS FOR REPLYING BACK I RWALLY DO.

[OfficialMrFunguin]

I have an exam tomorrow and I was thinking of skipping it (naughty me) because of this. You made it so simple! I am going to fly through that exam. Thanks dude!
