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?

yes
OpenStudy (studygurl14):
next, find the median.
(mean is slightly harder)
OpenStudy (anonymous):

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.
