Clean data is a teaching convenience
Every tutorial dataset is tidy because the tutorial is teaching a technique.
Real data is not. Dates in four formats, duplicated records with slightly
different spellings, missing values that mean three different things, and a
column somebody typed free text into. Handling that is a large part of what the
work actually is, and it is the part most courses skip because it is not
photogenic.
All four projects here use data with real problems in it, deliberately.
The statistics module is the one to take seriously
Everybody wants to reach machine learning by week six.
The students who struggle later are the ones who skimmed distributions,
sampling and what a p-value does not mean. They can fit a model and cannot tell
whether the result is an artefact — which is worse than not fitting one, because
it produces confident wrong answers that somebody acts on.
A baseline before every model, always. That single habit separates an analyst
worth hiring from one who has completed a course.
An honest word about the market
This field was oversold for several years and a lot of people paid for courses on
promises that did not hold.
The realistic picture now: entry roles are usually analyst-shaped, projects
matter far more than certificates, and most NCR data work sits in Gurgaon, Noida
and central Delhi rather than East Delhi. Expect a commute, a relocation, or a
competitive remote search.
None of that makes it a bad choice. It makes it a choice worth entering with open
eyes, and anyone telling you a six-month course leads directly to a data
scientist title is selling something.
If you want to be employable sooner
Say so, and look at Data Analytics instead.
It is shorter, aimed at answering business questions with SQL, Excel and Power
BI, and there is more entry-level demand for it — including in finance and
operations roles much closer to home. Several students take that first and come
back for this once they are working.
Getting there
S-551, School Block, Nehru Enclave, Shakarpur — walking distance from Laxmi Nagar
metro. Evening and weekend batches exist for people already working.
