About Correlation Coefficient

Calculate correlation coefficient to measure the strength of relationship between two datasets.

How to Use:

  1. Enter first dataset (x values)
  2. Enter second dataset (y values)
  3. Get correlation coefficient (-1 to +1)

Formula Used:

r = Σ[(xi - x̄)(yi - ȳ)] / √[Σ(xi - x̄)²Σ(yi - ȳ)²]

Examples:

  • Strong positive correlation: r = 0.85

Common Use Cases:

  • Data analysis
  • Research studies
  • Business intelligence
  • Scientific research
  • Predictive modeling
