Conducting a regression analysis using raw data | Year 12 Further Maths Units 3 and 4 | MaffsGuru

This is the final video in this series dealing with regression analysis for the Core Data component of the Further Maths Units 3 and 4 course. Building on the previous three videos it looks at one last example of how to perform a regression analysis when you've been provided some data. It looks at the style of report you can write and how you can use the CAS to help you. VCAA questions are completed at the end of the video which link to the theory already covered.

Performing a regression analysis | Year 12 Further Maths Units 3 and 4 | MaffsGuru.com

This is the third video in this series for the Further Maths Units 3 and 4 course dealing with Data Analysis for the Core Modules. In previous videos I have looked at what the least-squares regression line is and how we can calculate it by hand and using the CAS. Using the prior learning I am going to show you how to do a regression analysis and write a "kick-butt" report which should see those people at VCAA hail you as a Maths God.

Determining the equation of the least squares line | Year 12 Further Maths | MaffsGuru.com

This is the second video in a series on Regression Analysis and Least-squares regression lines. It builds on theory of the previous video by taking actual examples and fitting least-squares regression lines to the data. Full instructions are given to allow questions to be solved by hand and using the CAS. VCAA exam questions from recent VCE examinations are also used at the end of the video. All of the above delivered using the unique style the MaffsGuru has!

Standard Deviation | Year 10 Maths | MaffsGuru

This video looks at how and why we find the standard deviation of a set of numbers. We know that the IQR and Range are taken as measures of centre around the median. The standard deviation is a measure of centre around the mean. A number of worked examples are covered using both scientific calculators and CAS. It fully explains the formula and how we can use it to find the standard deviation. There is also a mention of the dreaded exams which happen at the end of school and how the standard deviation is used! This video is one of my favourites.
