OpenStudy (anonymous):

What is the interquartile range (IQR) of the data?

OpenStudy (studygurl14):

What data?

OpenStudy (studygurl14):

OpenStudy (studygurl14):

First step. Find the median of the data.

OpenStudy (anonymous):

3.5

OpenStudy (anonymous):

43.5

OpenStudy (studygurl14):

No.

OpenStudy (studygurl14):

Can you show me how you found 43.5?

OpenStudy (anonymous):

its 47.5 though cause theres six on each side so theres not a middle number so you go 47.5 which is in the middle

OpenStudy (anonymous):

right?

OpenStudy (studygurl14):

No...What middle numbers do you get?

OpenStudy (anonymous):

theres 12 numbers there i can't find the middle

OpenStudy (studygurl14):

OpenStudy (anonymous):

ooohhhh like 45 you go in the middle of the numbers

OpenStudy (anonymous):

@StudyGurl14

OpenStudy (studygurl14):

Correct. 45 is the median. Now split the numbers and find the medians of the first half and of teh second half.

OpenStudy (anonymous):

OpenStudy (studygurl14):

Find median of 31, 33, 37, 40, 40, 43, 45 and of 45, 47, 48, 50, 52, 56, 58
