A strong positive linear correlation between rainfall and the number of Oranges produced does not necessarily imply causation. While increased rainfall may provide better growing conditions for orange trees, other factors could also influence fruit production, such as soil quality, temperature, or tree health. Correlation indicates a relationship, but it does not confirm that one variable directly causes changes in the other. To establish causation, further investigation and controlled studies would be needed.
Positive correlation is a relationship between two variables in which both variables move in tandem that is in the same direction.
I would assume a negative correlation. More TV sets per home = less newspaper circulation.
That's correct. The correlation between two suitable variables in a data set might be any value between -1 and 1, including 0.
Strong and positive
No, it depends upon the size of the coefficient of correlation: the closer to ±1 the stronger the correlation.When the correlation coefficient is positive, one variable increases as the other increases; when negative one increases as the other decreases.
A Pearson correlation measures the strength and direction of a linear relationship between two continuous variables, ranging from -1 (perfect negative correlation) to 1 (perfect positive correlation). An example could be studying the correlation between the amount of rainfall and crop yield in agricultural research to understand how variations in rainfall affect crop productivity.
Positive correlation has a positive slope and negative correlation has a negative slope.
A positive correlation between two variables means that there is a direct correlation between the variables. As one variable increases, the other variable will also increase.

Yes
No, it is an integer number. Correlations happen among various different things. A non-zero correlation means that the things interact or depend on each other. A zero correlation means they don't. Examples: There is a positive correlation between how much you eat and how much you weigh. There is a zero correlation between the color of your car and its gas mileage. There is a positive correlation between how far the volume control is turned up and the sound pressure level that you hear. There is a negative correlation between the air temperature and the sales of sweaters.
Yes, a correlation coefficient of 0.92 indicates a strong positive correlation between two variables. This means that as one variable increases, the other variable tends to increase as well, and the relationship between them is quite close. Correlation coefficients range from -1 to 1, with values closer to 1 signifying a stronger positive correlation.
The correlation can be anything between +1 (strong positive correlation), passing through zero (no correlation), to -1 (strong negative correlation).
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.
If the two variables increase together and decrease together AND in a linear fashion, the correlation is positive. If one increases when the other decreases, again, in a linear fashion, the correlation is negative.
Either +1 (strongest possible positive correlation between the variables) or -1 (strongest possible negativecorrelation between the variables).
Only in the case of a positive outcome
