When $$a \ne 0$$, there are two solutions to $$ax^2 + bx + c = 0$$ and they are $$x = {-b \pm \sqrt{b^2-4ac} \over 2a}.$$ $H_0: \mu = 2.5\quad vs\quad H_a: \mu > 2.5$ $$ax^2 + bx + c = 0$$ One may readily verify that if $\sum_{i=0}^n i^2 = \frac{(n^2+n)(2n+1)}{6}$ and $$g$$ are continuous functions on $D$ then the functions $f+g$, $f-g$ and $f.g$ are continuous. If in addition $g$ is everywhere non-zero then $f/g$ is continuous.

Mission Statement

What is the mission statement of this blog?

I am writing this blog for a couple of reasons.  I have heard that teaching is one of the best ways to learn because you have to learn things twice.  You learn the material for the first time for yourself, then you learn it a second time when you explain it to someone else.

This summer I have spent a lot of time working on data science, python, machine learning, and statistics.  My process has been haphazard at best and lacked direction.  I had tons of drive and motivation, but no north star to guide my effort.  As I work to find that direction, I hope to provide a bit of guidance as to a better way to learn data science.

I think we always want to do cool, interesting things at the expense of the fundamentals.  I want to provide a place where people can see and learn the fundamentals of data science.  I also plan on tackling more advanced topics but first I need to build a strong foundation of knowledge.

What is the goal of this blog?
1) To help one person in their data science journey.
2) To help me learn and improve my data science knowledge.

What is the mission statement of this blog?
To learn and grow as a data scientist, and help others do the same.
