Split analyzing data and reporting results episode into two separate sections

The analyzing data section is long at the moment and I think can stand alone as its own "episode".

Then the "reporting results" section could come out as its own "communicating your findings" episode at the end.

Locate the lesson content containing the "analyzing data" and "reporting results" sections, then read the surrounding episode structure before editing. Done means the analyzing data material stands as its own episode and reporting results is a separate final episode titled "communicating your findings".
