Which of the following is a way to reduce "noise" in the data? Throw out data points that you don't like. Take the correlation coefficient of the data. Average the data. Take the standard deviation of the data.

OpenStudy (unklerhaukus):

If you through out the noisy ones... that should work, but its not very scientific

OpenStudy (unklerhaukus):

taking the correlation coefficient, or the standard deviation... isn't going to change the data is it?

OpenStudy (daniellelovee):

no

OpenStudy (unklerhaukus):

if you have a few separate measurement of the same point, i guess that you could average them,

OpenStudy (unklerhaukus):

i'm not sure.

OpenStudy (daniellelovee):

so according to you C is the most logical right?

OpenStudy (unklerhaukus):

What kinda of data is it?

OpenStudy (daniellelovee):

idk that is all it says

OpenStudy (unklerhaukus):

I think A and C are both ways to reduce noise in the data.

OpenStudy (daniellelovee):

yeah but I think C is better

OpenStudy (unklerhaukus):

If you can only pick one, i probably would go with C.

OpenStudy (unklerhaukus):

In practice though, I have certainly been guilty of option A.

OpenStudy (unklerhaukus):

In practice, averaging data mean you need to take much more measurements.

OpenStudy (daniellelovee):

alright thank you very much :)

OpenStudy (unklerhaukus):

The correlation coefficient and standard deviation will tell you how noisy your data is, but it won't fix it.
