Quick Answer: What Does It Mean If Pearson Correlation Is Negative?

How do I interpret a negative correlation in SPSS?

The negative correlation means that as one of the variables increases, the other tends to decrease, and vice versa.

If the negative numbers were positive instead this analysis would show a significant positive correlation..

Can you have negative correlation?

A negative correlation means that there is an inverse relationship between two variables – when one variable decreases, the other increases. The vice versa is a negative correlation too, in which one variable increases and the other decreases.

How do you interpret a weak negative correlation?

Negative correlation or inverse correlation is a relationship between two variables whereby they move in opposite directions. If variables X and Y have a negative correlation (or are negatively correlated), as X increases in value, Y will decrease; similarly, if X decreases in value, Y will increase.

Is a strong or weak correlation?

Influential outliers are points in a data set that increase the correlation coefficient. In Figure 1 the correlation between and is strong ( ).

What number is a weak correlation?

r > 0 indicates a positive association. r < 0 indicates a negative association. Values of r near 0 indicate a very weak linear relationship. The strength of the linear relationship increases as r moves away from 0 toward -1 or 1.

What is an example of zero correlation?

A zero correlation exists when there is no relationship between two variables. For example there is no relationship between the amount of tea drunk and level of intelligence.

How do you interpret correlation results?

A correlation close to 0 indicates no linear relationship between the variables. The sign of the coefficient indicates the direction of the relationship. If both variables tend to increase or decrease together, the coefficient is positive, and the line that represents the correlation slopes upward.

What is the difference between positive correlation and negative correlation in psychology?

A positive correlation means that the variables move in the same direction. Put another way, it means that as one variable increases so does the other, and conversely, when one variable decreases so does the other. A negative correlation means that the variables move in opposite directions.

What does a negative Pearson correlation coefficient mean?

A negative correlation describes the extent to which two variables move in opposite directions. For example, for two variables, X and Y, an increase in X is associated with a decrease in Y. A negative correlation coefficient is also referred to as an inverse correlation.

What does it mean when correlation is negative?

A negative correlation between two variables means that one variable increases whenever the other decreases. … Perfect negative correlation means that the relationship is demonstrated consistently over time. A decrease in one variable predictably meets with a comparable increase in the other.

What does a negative R value mean?

A negative r values indicates that as one variable increases the other variable decreases, and an r of -1 indicates that knowing the value of one variable allows perfect prediction of the other. A correlation coefficient of 0 indicates no relationship between the variables (random scatter of the points).

What is an example of a weak correlation?

If the cloud is very flat or vertical, there is a weak correlation. Earthquake magnitude and the depth at which it was measured is therefore weakly correlated, as you can see the scatter plot is nearly flat.
