how to clean up data on a small and larger scale

[kimpham54]

• [ ] jburnford gives many suggestions about adding some more detail, justification, and apparatus to make the significance of the lesson clearer. I think for most you can respond to them in the text of the lesson to clear things up. In cases like cleaning up the data, I think you could mention how to do it on a small scale on Excel, and provide suggest some links to other options that you might do on a larger scale?
