What is data analytics?
It is the work of examining data to answer business questions. Analysts move through four kinds of questions, from "what happened" to "what should we do".
Better questions, better decisions
A manager asks why sales dropped or which customers will leave. An analyst finds the answer in the data and explains it in plain words and clear charts. That skill is useful in every department.
What happened?
Summaries, trends and dashboards of past results.
Why did it happen?
Dig into causes by comparing groups and time periods.
What may happen?
Use patterns to forecast demand, risk or behavior.
What should we do?
Recommend actions and test their likely impact.
The six steps of every analysis
This is the routine you will practice again and again, on real data sets.
Ask
Define the business question and what a good answer looks like.
Collect
Pull data from spreadsheets, databases and business systems.
Clean
Fix errors, duplicates and gaps so the numbers can be trusted.
Analyze
Use SQL, Python and statistics to find patterns and drivers.
Visualize
Build charts and dashboards that make the message obvious.
Decide
Present findings, recommend action and follow up on results.

Questions people ask
Do I need coding experience?
No. You start with spreadsheets and SQL. Python is introduced gently and is optional for many analyst roles.
Do I need strong math?
Basic school-level math is enough. The course teaches the statistics you actually use at work.
Which tool should I learn first?
Start with Excel, then SQL. These two cover most day-to-day analyst work and make every other tool easier.
What is the difference between a data analyst and a data scientist?
Analysts explain what happened and why using existing data. Scientists build predictive models. Many people start as analysts and move on.
