Hello Rosebella,

I've signed up to review your modifications to the "Negative Relationship" article, but I can't seem to find the changes. Will you be posting them to your sandbox, or should I look elsewhere?Vs2357 (talk) 02:08, 24 March 2018 (UTC)

Your explanation of a negative relationship is clear and straightforward. There are just a couple of suggestions I have for improvement:

1) "The correlation coefficient, which is a number between 0 and 1, determines whether the two variables have a positive or negative relationship."

You might mention that the correlation coefficient, which is between -1 and 1, also gives the strength of the relationship.

2) "If the correlation coefficient is close to -1 or close to -1."

This seems to be a typographical error, as it should just be "close to -1" for highly negatively related. You could also mention that a value close to 1 would be highly positively correlated.

Hello Rosebella, First, The correlation coefficient is between the -1 and +1. This is positive relationship if the correlation coefficient is positive. So, This is negative relationship if the correlation coefficient is negative. Second, this is Perfect negative correlation if the correlation coefficient is equal to -1. Third, The higher the absolute value of the correlation coefficient is, the higher the correlation between the variables is. Peng Song

Thank you Peng RosebellaCapio (talk) 17:03, 8 May 2018 (UTC) I appreciate the references you provided. You might also provide a link to the "Statistical Association" article for additional information.Vs2357 (talk) 04:10, 23 April 2018 (UTC)

Hi Valerie,

Thanks for the feedback. For this work, I just added some more points to the previous article, provided an example and gave two references since the original post had just a link to a webpage which didn't serve as a good source of reference. Thanks for pointing out the typographical error and also for your suggestion. I will also work on providing the link to the Statistical Association. RosebellaCapio (talk)

If you click on the "1" for the second reference, it takes you to the pdf in question.
