Hunter wants to prove to his parents that playing computer games while he studies for tests will help him get better grades. He decides to ask 30 of his friends if they play computer games while they study for their tests and what their grades are. He finds that his friends who have high grades also play computer games while they do their homework. He tells his parents that he has proven that playing games while studying for tests will cause his grades to improve. What mistake has Hunter made?
maybe he meant to say that it wouldnt help his grades
do u have choices
Yup, one second...
1. He did not use a random sample, and he tried to show cause and effect with an experiment. 2. He did not use a random sample, and he tried to show cause and effect with an observational study. 3. He did not separate his friends into different groups, and he didn't apply a treatment. 4. He did not separate his friends into different groups, and he used a survey to collect data.
hang on a sec
they all kinda seem true except for the first one
that crosses off the 2nd one as well
i would say the last one
yeah i think so
is it correct? im almost positive
are u dead?? lol
the kid kinda just asked his friends he didnt separate them into groups and try it out or anything
The last one, huh... Lol, sorry, I went and started working on other questions x-x I'll have to see, when I finish the test
i gave u a medal too
It doesn't really seem like the last one, to me, though... idk, it seems simple but it's confusing x-x
I gave you one, haha ^^
fan? i am ur fan now? lol
Mmm. I guess ill fan if it's right..
i became ur fan its only fair lol XD
I don't think it's the last answer because I don't think using a survey is technically considered a "Mistake"
i have no idea
that one just made the most sense to me
what are u on a test for?
im on one for summer school
I think it's the 2nd one, " He did not use a random sample, and he tried to show cause and effect with an observational study." Since he simply asked his friends, without gathering any real tangible or reliable information. Plus, he already knew the subjects being asked, so they could've just told him what he wanted to hear...
I'm taking online school for extra credit ^^
ah yes that makes much more sense but what are u on a test for???
for me Alegebra 1
i failed my classes big time last year
Ah... that's unfortunate, haha ^^
it was my fault i hate doing work im lazy af
Most people are (not excluding myself), so it's completely understandable ^^
