I& #39;m auditing a course on network analysis (in principle, fascinating and powerful with lots of applications), and the first assignment sample data is... employee relationships, where -100 = enemies and +100 = friends.

I just. What. No.

So I& #39;m in a mood and decided to write down my own questions:

Why would an employer have data on employees& #39; relationships?

Assuming such a thing is possible, is it ethical?

Where would this data come from? (2/5)

How are relationship values, from -100 = enemies to +100 = best friends, defined?

How are such values measured?

Have you thought that perhaps human relationships can& #39;t be quantified in such a way? (3/5)

Given all of the above, what meaning would a Pearson correlation coefficient between these "relationship scores" and "movie preferences" even have?

Shouldn& #39;t data scientists be trained to ask these questions of their data? (4/5)

I am not hopeful these questions will be adequately answered. The instructors will fail their first assignment. (end thread)
