how does your material cover this?
What do you mean? I don't understand your question.
you are taking a course i assume, it has material that covers the contents of that course ... when you read the material, how did it present a solution process.
im just not sure how your course defines "a good line of best fit"
Well for this particular question I looked back in my chapters lesson on analyzing data and I couldn't find a question particularly worded like this. Thats why Im confused. Im not exactly sure how to answer this.
I can give you the answer choices?
answer choices might be helpful ...
as far as residual analysis goes ... this is a fairly good link http://stattrek.com/regression/residual-analysis.aspx
A. No, the equation is not a good fit because the sum of the residuals is a large number. B. No, the equation is not a good fit because the residuals are all far from zero. C. Yes, the equation is a good fit because the residuals are all far from zero. D. Yes, the equation is a good fit because the sum of the residuals is a small number.
Sorry I had to type all of them.
I think its A. But Im not positive
the sum of the residuals is 1, and the mean is 1/6 B is of no consequence to me, and C is just a rewording of B so I would say it is between A and D, all depends on how the material you have defines "large/small number"
how "good" of a best fit it is? ... i dont think i have ever covered that tho. which is why i defered to your material for more context
I think Im going to go with A
Thankyou for your help
my best guess would be A as well, but i just cant verify it
