Summary
Description
This is the next video in the series for data analysis and the General Maths Units 1 and 2 course. I now take a look at how to interpret a scatter plot having used previous lessons to construct them (by hand and using the CAS). In this course it's important to be able to describe the data. Taking a table of values and turning it into a graph is all well and good, but we then need to use technical language to describe it. This video uses a number of examples to explain the theory and guide you through what you have to write.
