## FAQs

### Q.What is Pearson’s correlation coefficient?

Pearson’s correlation coefficient, also known as Pearson’s r, is a statistical measure of the linear relationship between two variables. It ranges from -1 to 1, with a value of 0 indicating no correlation, a value of 1 indicating a perfect positive correlation, and a value of -1 indicating a perfect negative correlation.

### Q.How is Pearson’s r calculated?

Pearson’s r is calculated using the following formula:

``````r = (∑(x - x̄)(y - ȳ)) / √(∑(x - x̄)²)(∑(y - ȳ)²))
``````

where:

• x and y are the two variables being correlated

• x̄ and ȳ are the means of x and y, respectively

• ∑ is the summation symbol

### Q.What is the difference between Pearson’s r and Spearman’s rho?

Pearson’s r and Spearman’s rho are both measures of correlation, but they differ in how they calculate the relationship between two variables. Pearson’s r calculates the linear relationship between two variables, while Spearman’s rho calculates the monotonic relationship between two variables. A monotonic relationship is a relationship where the two variables change in the same direction, but not necessarily at a constant rate.

### Q.How do I interpret the p-value for Pearson’s r?

The p-value for Pearson’s r is the probability of obtaining a correlation coefficient as large or larger than the observed correlation coefficient, assuming that there is no true correlation between the two variables. A p-value of less than 0.05 is generally considered to be statistically significant, meaning that there is a less than 5% chance of obtaining the observed correlation coefficient if there is no true correlation between the two variables.

## Conclusion

Pearson’s correlation coefficient is a powerful tool for measuring the linear relationship between two variables. It can be used to assess the strength and direction of a relationship, as well as to test for statistical significance. However, it is important to note that Pearson’s r is only a measure of linear correlation. It cannot detect non-linear relationships between two variables.
