Could you take a screen shot of the columns?

OpenStudy (anonymous):

yeah give me a sec

OpenStudy (anonymous):

@StudyGurl14

OpenStudy (anonymous):

help anyone

OpenStudy (anonymous):

i couldn't take the screen shots all it said was copy or search it

OpenStudy (studygurl14):

Okay, so first you could find mode. It is the easiest. Mode means what number has the highest frequency, aka "most often" appeared

OpenStudy (anonymous):

Wait i don't get it

OpenStudy (studygurl14):

Look at the stem-and-leaf plot. Which number shows up more than once?

OpenStudy (anonymous):

wait i think i know what you mean

OpenStudy (anonymous):

give me a second

OpenStudy (anonymous):

62,65,65,68,72,74,75,79,88

OpenStudy (anonymous):

the number that shows more is 65

OpenStudy (studygurl14):

correct. so that's your mode

OpenStudy (studygurl14):

Next, let's do range. Range is the maximum minus the minimum

OpenStudy (anonymous):

so the max and the mini

OpenStudy (anonymous):

im not sure i know what minus

OpenStudy (anonymous):

means

OpenStudy (studygurl14):

minus, meaning subtract

OpenStudy (anonymous):

88 is the greatest 62 is the smallest

OpenStudy (studygurl14):

right, so 88-62

OpenStudy (anonymous):

so i subtract 88 and 63?

OpenStudy (anonymous):

26

OpenStudy (studygurl14):

yep, that's your range

OpenStudy (anonymous):

yes

OpenStudy (studygurl14):

next, find the median. (mean is slightly harder)

OpenStudy (anonymous):

oh ok

OpenStudy (studygurl14):

you already listed the numbers in order from least to greatest. Cross off one from each end one by one until you get either 1 or two numbers int he middle.

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

72

OpenStudy (studygurl14):

not quite |dw:1427907764907:dw|
