me too if i dont finish theses last assignments right no I cant take my final exam and If I cant take my final exam I am going to stay back
I am almost in teaars here people i need help
the last thing you have does is to plot the data, what happens next?
im not sure I need someone to go through the step with me thats why im here
the question says you have plotted the data, and already have a line of best fit, the options are A plot the data... [already complete] B offer a conclusion C draw a line of best fit [already complete] D find correlation coefficient
how can you offer a conclusion without first finding a quantitative measure ?
D I think becuase it's the legitmitlly the most logical
becuase you are right you cant just offer a conclusion
I cant just go with what makes sense I need to make sure I choose the best answer or else I will not be going to be able to go to highschool
You have four options, presumably one is correct, and three are incorrect. If you have found that option D is more correct than A,B,C, D must be the correct option.
I know but they pressure here is imense I think it's d but I have never been very good at math.... There is a 25% percent chance I will get it right
There is a 25% chance if you don't read the question and simply guess. We read the question, and ruled out two of the option immediately. This left us with two options and and 50% chance of guessing right. Then we used reason, to assert that one of the remaining options made more sense than the other remaining option. If our reasoning is sound, we have found the correct option with 100% probability.
do you think you might be able to walk me through the last two questions?
according to http://mathbits.com/MathBits/TISection/Statistics2/correlation.htm " A correlation greater than 0.8 is generally described as strong, whereas a correlation less than 0.5 is generally described as weak. "
so what do you think about a correlation coefficient of 0.67
at first I thought maybe it was b but now im not to sure
Are there only two options here?
oh, right i see all four options now
A: Yes, everyone who doesn't exercise is by definition unhealthy for this to be true , we would expect the correlation coefficient to very close to 1.00
okay so not a
B: Yes, the correlation coefficient is above 0.5, so that implies causation hmmm 0.67 is above 0.50
C: No, the data are only weakly correlated and may people are healthy who don't exercise for this to be true we would expect correlation to be <0.50
this is true
your correlation is 0.67 so that's >0.5 it's not a weak one
my spelling sucks
D: No, poor health and not exercising are completely unrelated for this to be true we would expect correlation to be close to 0.00
obviously not C and D. doesn't make sense if your correlation is above 0.5
so wouldn't it be b?
ready for my last question of the day
yeap, there is significant correlation
What do you think of the options? Some of the statements in the options are too strong, can you rule them out?
so Michele plays better than other teams and watches videos. wow !
i dont think it can be a becuase it true, you can see how the other team play and attacks
i agree, option A cannot be right, the statement is too strong
its not d because we have information... right?
I think it's double edge sword 1. she is already good before watching videos of other teams 2. she is a horrible player so she watches videos and copies moves from other teams
this is hard....you are right it's a double edge sword
getting good at soccer requires skill and practice.
Which is the correct option @bobobox ?
I think b is ridiculous. Players can't copy everything perfectly without messing it up.
i think it's c becuase I can watch all the soccor in the world and I wont be playing at the world cup
what do you guys think
yeah, watching videos and playing better did correlate, but we cannot draw any conclusion about causation, there are many other factors at play
wait so what about d
we concluded that there was a correlation
there are other reasons to why she played better - extra practice - after school practice - private coaching
okay so c
okay that right!!!! But the question we did before this was wrong
Are you sure?
hmmm i suppose a correlation of 0.67 doesn't really imply a causation, it just suggests one
but 0.67 is much greater than 0.50, it's not a weak correlation, unless the thresholds i got form that web-sight are way off
Positive but that's okay I got a 70 exactly so I'm happy
what was the answer they wanted?
the other options all seem worse
WHAT! Ok I'm glad that the last question was right but yeah I agree with Unkle. what do they want?
and it's website xD
my spelling sucks tooo
It's Laurel springs school and they don't tell you the right answer they just say it's wrong
either the site Unkle got was wrong or they are stupid
that's a private school? O_O!
Good job @UnkleRhaukus and @UsukiDoll
assuming Laurel springs school is right: i guess it has to be C: "No, the data are only weakly correlated and may people are healthy who don't exercise" and that the threshold they are using is <0.70 , is weak correlation.
Agreed I could have never done that without you guys
OH WOW! How does Physical Education work in an online school XD
i had to go to a gym at my high school
Remember that even a perfect correlation, doesn't imply causation.
