Complete the Hypothesis Case Study Part 1 tutorial. It is not a complete case study; it is just the steps you might take to do Graph Analysis. I have provided sample code for you to use as you go through the tutorial. I need you to prove me comments out each step and run them separately so I can fully understand what you are doing for each step of the analysis.



(I am using the first part of it to practice Graphic Analytics but the updates to anaconda missed up some of the packages and I can’t run python.)


I got some of the code done - the data set is large (205mb)


I will have to put it in a dropbox link




Testing Hypothesis Exercise Complete the Hypothesis Case Study Part 1 tutorial. It is not a complete case study; it is just the steps you might take to do Graph Analysis. I have provided sample code for you to use as you go through the tutorial.
