## What does negative Pearson correlation mean?

The most commonly used correlation coefficient is the Pearson coefficient, which ranges from -1.0 to +1.0. A positive correlation indicates two variables that tend to move in the same direction. A negative correlation indicates two variables that tend to move in opposite directions.

**How do you interpret Pearson correlation?**

High degree: If the coefficient value lies between ± 0.50 and ± 1, then it is said to be a strong correlation. Moderate degree: If the value lies between ± 0.30 and ± 0.49, then it is said to be a medium correlation. Low degree: When the value lies below + . 29, then it is said to be a small correlation.

### What does a correlation of .64 mean?

That is, a correlation between two variables equal to . 64 is the same strength of relationship as the correlation of . 64 for two entirely different variables.

**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 a good Pearson correlation value?

A calculated number greater than 1.0 or less than -1.0 means that there was an error in the correlation measurement. A correlation of -1.0 shows a perfect negative correlation, while a correlation of 1.0 shows a perfect positive correlation.

**What is a strong negative correlation?**

A strong negative correlation, on the other hand, indicates a strong connection between the two variables, but that one goes up whenever the other one goes down. For example, a correlation of -0.97 is a strong negative correlation, whereas a correlation of 0.10 indicates a weak positive correlation.

## Is .64 a strong correlation?

Strength of relationship The correlation between two variables is considered to be strong if the absolute value of r is greater than 0.75.

**Is 0.15 A strong correlation?**

For a natural/social/economics science student, a correlation coefficient higher than 0.6 is enough. Correlation coefficient values below 0.3 are considered to be weak; 0.3-0.7 are moderate; >0.7 are strong.

### How do you interpret an r?

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.
