Mode = number that appears the MOST. According to your data, that would be in the range of 165-170.
veronometry knows this better than me..
median is 170-175
Median is the middle number. Since you have 43 students, the median student would be student #22. This falls into the [170-175] range.
yay i just fanned u veronometry..
For the mean, does your teacher want you to take the middle number of each range?
wher the heck did you get 22 from?
Thanks Bahrom! :]
oh yea i got it
nvm
There are 43 students. The middle student would be student #22. In other words, if you listed out all the students from 1 to 43, 22 would be right smack in the middle (aka the median).
cool ! good stuuf :P
And, since the data isn't exact (they give you ranges versus the actual data), the BEST central tendency for this would be the MODE.
