12. What Does A Data Analyst Do?
First, they specialize.
There are no ends to tools and mathematical methods to
carry out data analysis. From social value based data
analysis that a UN data analyst will focus on to customer
behavior analysis that an ecommerce data analyst will focus
on to the general business data analysis I focus on.
Then they train themselves to be proficient in the tools they
need for their chosen field of application.

13. Should I Go Back To School?
To become a data analyst, yes and no.
Yes, you need to learn the foundational principles
of data analysis and the general mathematical
methods, especially those of importance to the
area of specialization you have chosen.
No, because you can learn them without going
back to the university. You can do self-study,
online course or a class-based crash course.

14. What Tools Do Data Analysts Use?
Generally, they use three categories of tools:
1. Data gathering, storing and retrieval tools
2. Data cleaning, transforming and analyzing tools
3. Data visualization, forecasting and workflow tools
Often, a tool can work across more than one category. Even
with all its limitations, Excel can be made to work across all
these categories. Then there are R, KNIME, Python, Tableau,
Power BI, Alteryx, RapidMiner, Cognos, SPSS, MATLAB etc.

21. What Does A Business Analyst Do?
Think about a project manager. He ensures the prompt and
within budget delivery of a project. What about before the
project? Who determines which company strategic project
to embark on? Who researches the options available and
which will deliver best result for the company? Who
coordinates between the management and other strategic
units of the company to drive through a company re-
orientating change project?
Answer: The Business Analyst.

22. Should I Go Back To School?
To become a business analyst, no.
It is more of a skill you acquire from professional training
classes and on the job experience. It is a lot more like
project management, except that it is not so much about
meeting set budgets and micro-managing allocated
resources. It is more about painting the big picture for
everyone in the company and being a central point of
contact between management and the other staff in
identifying and driving through a strategic change agenda.

23. What Tools Do Business Analysts Use?
First, a lot of good writing
and communications skill.
You will managing and
aligning a lot of divergent
opinions/agendas.

following books (I
recommend the Seven
Steps... one as I have it):
