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.
Positive correlation refers to a relationship between two variables where they move in the same direction, meaning an increase in one variable is associated with an increase in the other variable. Negative correlation, on the other hand, refers to a relationship where the variables move in opposite directions, so an increase in one variable is associated with a decrease in the other variable.
In 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.

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?
Not necessarily. Gram positive and gram negative bacteria can vary in size depending on the species. Both gram positive and gram negative bacteria can range in size from small cocci to long rod-shaped cells.
What blood types are the most common and the most rare?
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.
Feedback is when the body reacts in the same direction as a stimulus. Negative Positive?
Feedback can be both negative and positive. Negative feedback occurs when the body's response counteracts the stimulus, helping to maintain homeostasis. Positive feedback amplifies the stimulus, leading to a larger response.
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
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.
