wat number is this for @jim_thompson5910

- jim_thompson5910

it's for finding the five number summary

- jim_thompson5910

what five number summary do you get

- anonymous

how to find the iqr @jim_thompson5910

- jim_thompson5910

IQR = Q3 - Q1

- jim_thompson5910

Q1 is the first quartile
Q3 is the third quartile

so will it be 13 for Bryce and 1 for Brianna ?

- jim_thompson5910

I am not getting 13 for the IQR for Bryce. You made an error somewhere

- jim_thompson5910

you have the correct IQR for brianna

- anonymous

for Bryce I got 80 for the min. 85.5 for the FQ. 91 for the Med. 98.5 for the TQ and 100 for the max so when u subtract u get 13 for Bryce. what did u get @jim_thompson5910

- jim_thompson5910

Bryce
IQR = Q3 - Q1 = 98.5-81.5 = 17

- jim_thompson5910

btw the notation FQ and TQ should be replaced with Q1 and Q3

I see wea I went wrong thanks ...ok for number 2 I said Bryce should get it because he had the higher grades and iqr than Brianna...right? @jim_thompson5910

They seem to be split 50/50 in terms of who has larger scores
but Bryce does have larger Q3 and max values
however, in terms of consistency, brianna is more consistent since her IQR is lower

- anonymous

so how should I word it @jim_thompson5910

- jim_thompson5910

write out what you think and I'll look it over

- anonymous

the student I think should get the math award is Bryce because even though they are both split 50/50 for who has the higher grade he does have a higher IQR than Brianna which makes her more consistent. @jim_thompson5910

- jim_thompson5910

having a larger IQR means things are more spread out
which means that his grades aren't as consistent as brianna's grades
the larger IQR is not a good thing. It's better to be consistent and aim for a good grade as well

number 3 @jim_thompson5910

- jim_thompson5910

add up all of bryce's scores
then divide by 8 (there are 8 numbers in bryce's list)
