I agree with Fayez, I wish I could have watched this video earlier on in the week. It is interesting to see how corruption is so easily to notice in this graph.

The graph makes the corruption look so obvious, I think that's another good reason to be sure to do some basic graphing/visualization on data before actually starting any calculations.

Hello Professor, I hope you are well. I am still a little confused with what a binomial test is used for exactly. Is it just to see if there is a difference between observed and expected values? Please let me know and thank you!

I wish I had seen this before submitting Lab 3. It is very useful. It is interesting to see that the Islamic party initiated corruption. Based on the political environment at the time, I would have assumed the opposite to be true. I like how these methods can be used to analyze real life situations. I am seeing that more clearly now.

In the Lab 3 assignment, I wanted to do the Binomial test for the last question to test whether there is a discontinuity around the cutoff (two bins but I couldn't specify the arguments. Could you please show me the code for it? Thank you
