What is the median of the data set? {16, 15, 17, 19, 12, 11, 14, 14, 13, 11, 18, 15}

OpenStudy (gabbyalicorn):

give me a sec

OpenStudy (black_ninja123):

ok

Nnesha (nnesha):

medain = middle number of average or two middle number and number must be in numerical order

OpenStudy (astrophysics):

Median is the middle number, so you place the values in order and then find the middle :P.

OpenStudy (anonymous):

You need to put all the numbers in order from least to greatest

OpenStudy (gabbyalicorn):

I already know that -_-^ but thank you for telling me again 11, 11, 13, 14, 14, 15, 15, 16, 17, 18, 19 did i miss any numbers

Nnesha (nnesha):

OpenStudy (gabbyalicorn):

Okay, let me try again.

OpenStudy (black_ninja123):

OpenStudy (gabbyalicorn):

11, 11, 12, 13, 14, 14, 15, 15, 16, 17, 18, 19 now did i miss any numbers

OpenStudy (black_ninja123):

No

OpenStudy (astrophysics):

Looks good, so since we have to pair of middle numbers, lets take the average.

|dw:1434492572217:dw|

OpenStudy (astrophysics):

29/2, that looks good :)

OpenStudy (gabbyalicorn):

oh i was doing 2/ 29 XD oopa

OpenStudy (gabbyalicorn):

oops*

OpenStudy (astrophysics):

\[\frac{ 15+14 }{ 2 } \implies \frac{ 29 }{ 2 } = 14.5\]

OpenStudy (gabbyalicorn):

14.5 yepp

OpenStudy (astrophysics):
