The Correlation Calculator is a powerful tool that helps you measure the strength and direction of the relationship between two variables. By entering two sets of values, this calculator instantly computes the Pearson correlation coefficient (r), which ranges from -1 to +1. A value close to +1 indicates a strong positive relationship, while a value near -1 shows a strong negative relationship. This tool is highly useful for students, researchers, and professionals working with statistics, data analysis, and research projects. Designed to be fast, accurate, mobile-friendly, and WordPress-safe, the Correlation Calculator makes analyzing data simple and reliable.
