Have you heard that things are going up? Prices and the cost of living increase from year to year. Normally the cost of goods and services grow as a linear relation. Identifying a trend or a linear pattern may help you predict how much an item will cost in the future.

 

Module 3 is all about linear relations. You will work to answer the module question: How can situations be modelled by linear relations?

 

In this module you will focus on how statistics can be used to help make decisions. To do this, you will explore the lessons and questions in the table.
