Meyer — Toaster Regression from Dan Meyer on Vimeo.
I just ran the toasting times through Microsoft Excel 2010. The raw data is below.
I graphed the data and used trendlines to analyze the data. The first graph shows the linear regression.
The next graph is the exponential regression.
Finally, here is the quadratic regression.
Also on Dan's blog post, the darkness of the toast is estimated. The graph, with exponential regression, is below.
