are emily and i set?

Ok, so emily and I have all the criteria-i think.

2 populations: 6th and 7th graders and 8th and 9th graders

What we are comparing: who uses the computer more than an hour a night for non homework purposes.

Hypothesis: 6th and 7th graders will use the computer more than the 8th and 9th grades because of the lesser amount of hw they have.

Null: There is no difference between computer usage of 6 and 7th grades and 8 and 9th grades.



All good?

k, so...

when are we actually allowed to start collecting data?
and caleb, whats with the dragon thing? (julian said it was all you)

YO!@^%*($#

BENJAMIN VERVILLE!
we really need to figure out what's going on with our POW.
:) let's talk talk talk. very soon. like, right now. k, thanks.

Our Hypothesis

So me and deanna also forgot to post our hypothesis. Here it is: Hypothesis: 6th and 7th graders will use computers for non homework use more than 8th and 9th graders would. Null Hypothesis: There is no difference in 6th through 9th graders in regard to non homework computer use. :-)

So I Just wanted to know...

So whens the POW due?.....

Mistake in Me and Deanna's

So I wrote before that our two populations are boys and girls, but it is really junior high and high school, so 6th-7th grade vs. 8th-9th grade.

Me n' Andres's hypothesis

We consider skiing or snowboarding once a month at least for actually skiing or snowboarding... We will do 32 people... 16 for people who ski or snowboard and 16 don't... 8 from each group will be JH and 8 will be HS

We think that that skiers and snowboarders will like snow more.

Sara and Ben's idea..

Question:

Do you prefer cats or dogs?

Population:

Lower building (k-2) and 6th, 7th and 8th.

Me n' Andres's idea

I guess I should get this out here...

We are taking a random population of people from gunstock and people on the ski team and comparing them to people who are not in terms of "the likedge of snow" :p

Does that sound fancy enough?

our idea.... again

And to select people randomly, we'll choose every 3rd person... Will that work? 

and our populations are actually jr. high vs high school and our hypothesis is that jr. high will watch more television becuase they have less homework/more time and seem like the type of people that go home and watch tve. :)

Ideas.

Alright, so we should get all the ideas on here soon so we can start collecting data. Thanks :p

Collecting Data

When will we be able to collect our data? should we do that before or after vacation?

Emily and Deanna!

Our POW is going to be based off of:
Do you use the computer more than an hour for non-homework every night?
The populations will be boys and girls in 6th-9th grade.

our idea

Mine and micaela's question is: Do you spend more than 45 minutes a night watching TV? (Yes, or No... population will be JH and HS Boys and Girls)

PS: I don't get the whole dragon thing??????

great! thanks for this wonderful blog............................Julian your in charge of blogging for our team cause i dont have internet at home. thanks

Thanks!

Thanks for putting the blog caleb and julz!!
This should help out with a ton of problems we all may have!!!

-BENHAMEEN!!! :D

THINGS TO CONSIDER FOR YOUR PROJECT.

What are the 2 populations you are comparing? examples: boys/girls at SBS; boys/girls in NH; adults/teenagers; HS/JH at SBS. Once you know what your populations are, how do you select a representative sample without bias?

What are you comparing? Do you have some good reason to think that there might be a difference in the 2 populations?

And remember that expected values have to be 5 or greater - so pick something to compare where the populations are really divided, not overwhelmingly one-sided.

WHEN YOU HAVE AN IDEA - POST IT - let other people comment on it, question it, help you refine and craft your idea into a better form before you actually try it. THIS WILL NOT BE DUE BEFORE VACATION!

Hi - I'm on! -

Alright!

Alright! Looks mighty swell guys! So i don't really get the whole Dragon's Daily Drill, but i like it! So When's the POW due?

Woot!

Ok, here's our amazing math blog. Be sure to do the "Dragon's Daily Drill" on the sidebar on the right of the posts. :)
