The last entry for Statistics Diary will be about statistical diary. This series of diaries was for class assignment, and keeping it helped me practice relating things I learn in class to my day-to-day life. Sometimes I struggled to find topics I can write about, because nothing particularly "statistical" happened that day. That pushed me to ask my friends for inspiration, which often lead to interesting discussions. Coming from math background, I used to think of statistics as something objective like math. I realized that it's not always obvious how one can interpret statistics, or even agree on what is the statistics that matter or not. I'm quite surprised and proud that that I kept this diary regularly--I'm going to try to have some elements of statistics diary in my secret personal diaries from now on.
