Transformers - Analysing Turns Ratio and p.d. Equation Data

Analysis of the data from the experiment to investigate the transformer turns ratio equation.
A statistical investigation of the linear correlation between the turns ratio and p.d. ratio. This is done with fairly simple data but obviously the method can be applied to more complex data to see how closely aligned the data sets are to a linear correlation.
There is a worksheet to go with this experiment so that you can attempt the data analysis yourself. And the spreadsheet that I use is available as a free download. Get them both via the website here: physicshq.wixsite.com/alevelp...
Experiments with waves, like this one, are good practice for mandatory practicals for many physics specifications, such as OCR physics A, AQA A-Level physics, Edexcel A-Level physics, CPAC, PAG, practical endorsement.
Relevant concepts: transformers, electromagentic induction, step up, step down, r, r squared, correlation.
