Regression & Correlation

Explore how statistics studies relationships and trends between different variables.

Many quantities are connected to each other.

Regression and correlation help statistics study these relationships mathematically.


What This Topic Studies

This section studies:

  • relationships between variables
  • trends
  • prediction
  • data connections

Statistics studies how variables influence each other.


Why Humans Invented Regression Analysis

Scientists and economists needed mathematics for understanding relationships involving:

  • population growth
  • prices
  • weather
  • scientific measurements

Regression gradually became a major statistical tool.


Main Mathematical Ideas Introduced

This section introduces:

  • correlation
