Toolkit: Simple linear regression

Exclusive content on Boosty, video classes on YouTube, summaries and notes on Instagram, units 1~5 content in the best free textbook, class extracts on TikTok, text below. Have fun!

Chapter contents:

  • How to — how the tool works
  • Pros and cons — evaluation of the tool

  • Example — sample IA extract with the tool

The main purpose of simple linear regression is to demonstrate correlation and extrapolate the trends.

Just a reminder to keep a record of all the tools in the table below. As long as you can fill in all the cells of the table, you will be able to write a successful IA.

How the tool works

Simple linear regression refers to techniques to predict relationships between two variables (for example, costs and revenues). The IB BM syllabus includes four simple linear regression techniques: scatter diagram, line of best fit, correlation, and extrapolation. If you look at the picture below, you are very likely to understand how each of the four techniques works. If you need more information, continue reading.
