Phases of data analysis
There are different opinions on the distinct phases of data analysis. Sources like and have slightly different opinions. As such, these are not “rules” just suggestions.
My own experience is based on, but slightly different than, Wharton and John Hopkins, largely based on prior experience at Lucky8 . This page is organized from my own experiences, with strong doses of academia influence.
