Answer to a blog designed to look for flaws, where there is no such thing...

Read the link first, so you can followed the answer :D

The Angrymath blogger wrote about Udacity Statistics 101

 http://www.angrymath.com/2012/09/udacity-statistics-101.html

He wrote:“It feels like lack of planning…” That is a completely subjective approach, everybody can feel whatever. It is a particular emotion.

Sebastian’s weight… That is very personal; a woman generally speaking doesn’t use that example. A person can use it because it is very trivial for him, and the important part is the manipulation of the numbers; or also can used it because other data can be subjected to the rigorous scrutiny of the world.

The syllabus was done by a statistician engineer not by a statistician Angrymath… so, the language is correct because it was used in a very practical way. I can tell you beautiful and pretty, and means the same. The accuracy of the syllabus depends of the point of view of the user.

Terms and symbols…they were either written or said, so what is the problem? That is why is a video that you can repeat it, and also is for people that can go to any internet search engine and go deeply in anything, if not, you have the forums. That way the class was light and fun, I was not lost in definitions. I usually emphasized the difference between the symbols we use in samples, populations, or examples because it is very important in Quality research… when you are dealing with a computer software or program that is giving you the answer no matter how much data are you dealing with the terms start blending in the software or program so that is why it does not have that much importance, the answer, for practical purposes is going to be the same.

The words that the Angrymath blogger uses are religious, cardinal sin and unforgivable, legitimate good idea, and the phrase “beauty is the enemy of expression” are philosophically extreme and in Science or Math that does not count. The ways a person communicates it is entirely personal, and that is call style, if the phrases “Be amazed…” or “…if you don’t know the answer…” are perceived differently of what it is literally said, that is being subjective, and again it does not count for further speculation. I rather be challenged with an intuitive question than to just followed the lecture, and that approach is very good for learning.

In engineering we use many data from other sources, how deep we go into them it depends always in the practical approach we want to show, or is going to be useful… if an empirical rule needs to be established, then we can do another empirical one, called it in a very loose way “magical” and nobody believes that the ancient perception of the magic term is used.

The way Sebastian Thrun developed the formula for a normal curve it is actually one of the most practical, easy to understand ways I have seen without using complex math. It is entirely practical and useful for people interested in the use of a tool no how it was made.

To blink or not to blink? What does it matter if you are going to repeat the video…. “Thrun actually does finally explain the technique…” So, he did it!!! And that is his style, a very unique way of making the class interesting; you were supposed to be puzzled!!!

Final Exam Certification… well, Mr. Angrymath can give me his grade and who cares. If Sebastian Thrun gives me a grade, excuse me!!!!! OMG!!! One of the most intelligent persons in the whole planet. I am absolutely honored.

Hucksterism can be applied to Mr. Angrymath just because of his own nickname. Most people like to be motivated and confident and that was the purpose of the cheering. Other vocabulary is just not practical worldwide. It needs to be simple and people need to use the tools.

Udacity is improving and moving itself organically to maximize the learning of their students, so the suspicions of this blogger are totally unfounded.

The summary concludes in a total reverse of a new most rewarding attempt to share knowledge. It seems that some professors are really touched and shake by the new learning style. Flexibility, adaptation and relearning should be priorities instead of hopeless attacks. New technologies, reviews of old syllabus or specific approaches could be his new religion.
