Given the numbers 2, 2, 3, 4, 5, 8, 8, 9, 10, 15. Find the five-number summary. Low = _______, Q1 = _______, Median = _______, Q3 = _______, High = _______.

OpenStudy (ivettef365):

the low and high should be easy

OpenStudy (ivettef365):

do you know?

OpenStudy (pphalke):

no I can look up how to find low and high

OpenStudy (ivettef365):

what is the lowest number of the data

OpenStudy (pphalke):

2 is the lowest number

OpenStudy (ivettef365):

good so that is the low

OpenStudy (ivettef365):

same thing for the high

OpenStudy (pphalke):

the high is 15

OpenStudy (ivettef365):

correct

OpenStudy (ivettef365):

do you know how to find the median

OpenStudy (pphalke):

the middle number and its 8 right?

OpenStudy (ivettef365):

you have a total of 10 numbers on the data

OpenStudy (ivettef365):

so the middle numbers are 5, 8 2, 2, 3, 4, 5, 8, 8, 9, 10, 15

OpenStudy (ivettef365):

you add them and divide by 2

OpenStudy (pphalke):

how do I find q 1 and q 3 and also I got the median as 6.5

OpenStudy (ivettef365):

yest the median is correct

OpenStudy (ivettef365):

no to find the first quartile Q1, you divide the data in two parts, so you have the following: 2,2,3,4,5 and 8,8,9,10,15

OpenStudy (ivettef365):

find the median of the first half that is Q1 find the median of the second half that is Q3

OpenStudy (pphalke):

how do I do that?

OpenStudy (ivettef365):

what is the median of 2,2,3,4, 5

OpenStudy (pphalke):

add all the numbers here and divide by 2 I don't know the median I typed it in and got a fraction answer

OpenStudy (ivettef365):

no, just find the middle number
