This is the next video in this series for the General Maths Units 1 and 2 course. And what an awesome video I have for you. I take a look at how numerical variables can be related to each other and how you know which to plot on the x-axis and which to plot on the y-axis. Welcome to the world of response and explanatory variables. It's a really short video but rather important as, without it, you could make some very horrible mistakes. I use a number of worked examples and take the time to explain how to do them in my own unique way! Lots of humour whilst removing the smoke and mirrors.
This is another in the series looking at data for the General Maths Units 1 and 2 course. Having looked at how we can describe two variables on a scatter plot (or graph) we now look at how we can take raw data and turn it into a scatter plot. I look at how you can do it by hand and then how to use the CAS (it is a CAS course after all!). There are lots of worked examples with clear and easy to understand examples.
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.
