what five number summary do you get

Answer 9

how to find the iqr @jim_thompson5910

Answer 10

IQR = Q3 - Q1

Answer 11

Q1 is the first quartile
Q3 is the third quartile

Answer 12

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

Answer 13

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

Answer 14

you have the correct IQR for brianna

Answer 15

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

Answer 16

Bryce

IQR = Q3 - Q1 = 98.5-81.5 = 17

Answer 17

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

Answer 18

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

Answer 19

I got this comparison

Answer 20

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

Answer 21

so how should I word it @jim_thompson5910

Answer 22

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

Answer 23

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

Answer 24

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

Answer 25

number 3 @jim_thompson5910

Answer 26

add up all of bryce's scores

then divide by 8 (there are 8 numbers in bryce's list)
