January 19

When I was studying statistics in college, one day my IE 393 teacher said: There are two types of errors in statistics.
1- A TRUE null hypothesis can be incorrectly REJECTED (Type I error)
2- A FALSE null hypothesis can be fail to be rejected. (Type II Error)

He then gave an example for us to relate better
1- Convicting an innocent person (Type I error)
2- Failing to convict a guilty person (Type II Error)

As a student who tried to apply every "class knowledge" to life, I tried to do the same with this piece of info. It stick with me and as I would meet new people, I would consider these potential errors in my pre-judgments. I think I mostly commit the Type II. I dont know why I starting to think this.
I guess as I am getting ready to make a change in life and move to Turkey; I am scared of being judged by people and actually being a victim of Type I.... we will see I guess.

Bence hangi hatayı yaparsan yap, hakikati bilmediğinden, her iki önerme de doğru olabiliyor. Suçlu sandığın kişi suçsuz; Suçsuz bildiğin de günahkâr olabilir. Yani 1. tip yanılgı, 2. tipten gelebilir. Bu durum aynı zamanda tersinir.

Bilgi ne de önemli bir şey, bir diğer önemli şey ise ilgi.

Çok az şey bilip, kimseyle ilgilenmiyoruz.

Seni seviyorum.

Cool blog!

I am a teen and recently found out I am expecting a baby! I started a blog titled "In the life of a teenager" not expecting such a twist...But my life is getting quite interesting. Follow me, please! I ask for any advice or comments. Being 17 and pregnant is difficult.

Thank you so much!
Have a wonderful day :)
