I'm not sure what my xmax and xmins are do you mean the difference between my lower and upper bounds? http://assets.openstudy.com/updates/attachments/50785d74e4b0ed1dac50e148jennifersmart11350065660892screenshot20121012at1.10.44pm.png

well the idea is that class range is x_maxxmin divided by the number of classes.
 one year ago

helder_edwinBest ResponseYou've already chosen the best response.0
u get a class with equal to \[ \large \frac{430}{8}=5.375 \]

can be rounded up to 5.4

it's just intro to stats and it's algebra based. I don't think they want us to do anything too fancy.

hartnnBest ResponseYou've already chosen the best response.1
bins are just ranges of xaxis, like to construct a histogram from a continuous variable you first need to split the data into intervals, called bins. so here your bins are 05.5, 5.511.5....... and u have 8 bins in total
 one year ago

JenniferSmart1Best ResponseYou've already chosen the best response.1
so my bins would be my class boundaries. I labeled the upper and lower bounds
 one year ago

JenniferSmart1Best ResponseYou've already chosen the best response.1
" if you want to separate grades based on a 10 point scale 60, 70, 80, 90, 100 would be the bins" So I guess I'm using a 5 point scale and my bins would be....0, 5.5, 11.5...no?

hartnnBest ResponseYou've already chosen the best response.1
your bins does not have equal size....

I don't know anymore. I thought they have to be separated by 5...ooops I thought I had them spaced equally :S

i am going though it, so u have 8 classes. how did u find class width ?

\[\frac{\text{Largest data valuesmallest data value}}{\text{Desired number of classes}}\]

0 to 43 = 44 so 44/8 = 5.5 like this ?
 one year ago

hartnnBest ResponseYou've already chosen the best response.1
so the bins are : 0/5.5 5.5 11 11=16.5 and so on
 one year ago

JenniferSmart1Best ResponseYou've already chosen the best response.1
43/8=5.375 so I rounded it ...yes that's what I did...
 one year ago

hartnnBest ResponseYou've already chosen the best response.1
so u need to change your bins to 05.5, 5.511 , and so on..
 one year ago

JenniferSmart1Best ResponseYou've already chosen the best response.1
is a bin a range or a specific number? From the way they've written it's kinda confusing "if you want to separate grades based on a 10 point scale 60, 70, 80, 90, 100 would be the bins"
 one year ago

JenniferSmart1Best ResponseYou've already chosen the best response.1
wikihow could be wrong though
 one year ago

hartnnBest ResponseYou've already chosen the best response.1
a bin is an interval : 1st bin: 05.5 2nd bin: 5.511 so bin is range
 one year ago

hartnnBest ResponseYou've already chosen the best response.1
bin is not a number bin size or width is a number = class width

JenniferSmart1Best ResponseYou've already chosen the best response.1
ok so how do we proceed...the data analysis toolbox is confusing, I don't even know where to start http://assets.openstudy.com/updates/attachments/50785d74e4b0ed1dac50e148jennifersmart11350065660892screenshot20121012at1.10.44pm.png
