Bivariate data involves two variables and helps us explore how they relate. We use scatter plots to visualize relationships, look for positive or negative associations, and identify linear or non-linear patterns. Two-way tables help organize and analyze paired data.
🔍 Why It Matters
Bivariate analysis helps us understand how two variables relate to each other. This is essential in scientific research and business analysis for making predictions and informed decisions.
