Positive correletion between x and y means that x=ay+b, with a>0 so tha as y increases, so does the x. Now, negative correlation is the same, but with a<0 so that as y increases, x decreases. You have to be careful with the value of correlation coefficient it takes values in [-1,1]. values near 1(or -1) mean strong positive(or negative for -1) linear relation between x and y.

∙ 10y agoIn science, positive correlation is a general positive slope in something. Often times this is represented with a graph, using many points of data, for instance, height vs age would be a positive correlation. The meaning of positive correlation in both science and math are very, very similar. Only the scenarios they are used in differ.

Parathyroid glands is a negative or positive feed back?
Negative. There are VERY few positive feedback mechanisms in the body- the only one i know about is birth. Think of negative feedback and positive as a line.
What is the difference between positve and negative correlation?
Positive correlation has a positive slope and negative correlation has a negative slope.
What does the sign of the correlation coefficient tell you about the association?
Positive correlation = positive association Negative correlation = negative association
Is certain a negative connotation or positive correlation?
A positive correlation.
What are three types of correlations?
positive correlation-negative correlation and no correlation

It's a negative correlation because it is less than 0
What shows a correlation which may be positive or negative between two sets of data?
I believe you are asking how to identify a positive or negative correlation between two variables, for which you have data. I'll call these variables x and y. Of course, you can always calculate the correlation coefficient, but you can see the correlation from a graph. An x-y graph that shows a positive trend (slope positive) indicates a positive correlation. An x-y graph that shows a negative trend (slope negative) indicates a negative correlation.
How can you tell from a scatter plot wheather two variables have a positive correlation a negative correlation or no correlation?
Positive correlation = the slope of the scattered dots will rise from left to right (positive slope) Negative correlation = the slope of the scattered dots will fall from left to right (negative slope) No correlation = no real visible slope, the dots are too scattered to tell.
What are the trends of a line?
They can be positive correlation, negative correlation or no correlation depending on 'line of best fit'
Is 0.5 the strongest correlation coefficient?
No. The strongest correlation coefficient is +1 (positive correlation) and -1 (negative correlation).
What is the correlation on a graph?
a correlation on a graph is when the line of best fit is positive, negative or none.
Is the age of pets in a home and the number of pets in that home a positive negative or no correlation?
no correlation.
What is the data telling you with a positive or negative correlation?
If the data have a positive or negative correlation, it means the data have a linear relationship in the form of an equation of a line; or Y = mX + b.
