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.

What is blood type A positive plus A negative equal?
Blood type A positive plus A negative equals blood type A positive.
What bacteria is indole negative urea positive methyl red positive hydrogen sulfide positive and lactose negative?
Proteus vulgaris is a bacterium that fits this description. It is indole negative, urea positive, methyl red positive, hydrogen sulfide positive, and lactose negative. These characteristics are used in biochemical tests to help classify and identify different bacteria species.
Is gram positive bigger than gram negative?
Gram-positive bacteria and Gram-negative bacteria are different in their colouration when dyed and viewed with a light microscope. Gram-positive appear violet, and Gram-negative appear red. Gram-positive and Gram-negative classification, however, has nothing to do with size.
Can your blood type change from positive to negative?
No, your blood type cannot change from positive to negative. Blood type is determined by the presence or absence of certain antigens on red blood cells, not by the positive or negative Rh factor.

O positive O negative A positive A negative B positive B negative AB positive AB negative The rarest of all these blood types listed is AB negative making up 0.7% of the worlds population.
What is the difference between positve and negative correlation?

Is -.187 a positive or negative 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).
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 correlation on a graph?
a correlation on a graph is when the line of best fit is positive, negative or none.
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.
