# Pearson’s Correlation

**Use: **Pearson’s correlation measures the linear relationship between two continuous variables. It produces a correlation coefficient that ranges from -1 to 1, indicating the** strength and direction of the relationship.**

**Example:** Examining the relationship between hours of study and exam scores for a group of students to see if there's a linear correlation.

**Column Requirement:** Continuous data for both variables.

**Steps:**

Select two columns with continuous data (e.g., height and weight).

Check for a linear relationship between the variables.

Compute the Pearson correlation coefficient.

The coefficient ranges from -1 to 1, where 1 indicates a perfect positive linear relationship, -1 a perfect negative linear relationship, and 0 no linear relationship.
