Statistician
Statisticians turn data into dependable answers — whether a new medicine works, how many people live below a certain income, or which factors drive customer behaviour. It is a quiet but powerful profession behind surveys, clinical trials, economic policy and modern analytics.
- Main degree
- B.Sc and M.Sc in Statistics (or Mathematics with Statistics)
- Stream
- Class 12 with Mathematics
- Key exams
- ISI admission test, IIT JAM, CUET-PG, UPSC Indian Statistical Service
- Work settings
- Government, research, pharma, banks, analytics firms
Career overview
Statistics is the science of learning from data in the presence of uncertainty. Statisticians decide how data should be collected, choose the right methods to analyse it and judge how confident we can be in the results. Their work underpins official figures such as population and price data, medical research, quality control, and many data-science applications.
The career suits students who like mathematics but also want to apply it to real-world questions. A postgraduate degree is common for professional statistician roles, and programming has become an essential part of the job.
What does a statistician do?
A statistician may design a survey or experiment, decide sample sizes, clean and explore data, fit models and test hypotheses. In a clinical trial, for example, a biostatistician plans the analysis in advance and then determines whether differences between treatment groups are genuine or due to chance.
They also communicate findings through reports, tables and charts, and advise non-specialists on what the data can and cannot show. In government, statisticians run national surveys and compile official indicators; in business, they build forecasting and risk models.
Typical work environment
Statisticians work in government statistical offices, research institutes, universities, pharmaceutical and clinical research organisations, banks and insurers, market research companies and analytics or technology firms. Most work is computer-based using R, Python, SAS, SPSS or similar tools.
Survey statisticians may occasionally travel for field supervision. Hours are generally regular, with deadline pressure around reports, trial submissions or releases of official data.

Opportunities in India
India has a long tradition in statistics, with the Indian Statistical Institute, a national statistical system that runs large surveys, and a growing clinical research sector. The rise of data science has created new demand for people with rigorous statistical training, though employers increasingly expect strong programming skills as well.
Hyderabad and Telangana students have useful local options: the pharma and life-sciences cluster around Genome Valley and the city’s clinical research organisations need biostatisticians and statistical programmers (see Pharma and Life Sciences Careers in Hyderabad), while analytics teams in IT firms and global capability centres around HITEC City hire statistics graduates. State universities offer B.Sc and M.Sc Statistics, and state statistics departments recruit through notifications from bodies such as TGPSC.
International opportunities
Statisticians are needed worldwide in health research, government, finance and technology. Master’s and PhD programmes in statistics abroad often offer research and teaching assistantships.
Biostatistics in particular has international demand, though work visas and local experience requirements apply.
Advantages of this career

Future outlook
Demand for statistical skills continues to grow with data-driven decision-making in government, health and business. Clinical research, public health and risk modelling are steady employers of trained statisticians.
As automated tools make analysis easier, people who understand the underlying methods — and can spot misleading results — remain valuable.
Frequently asked questions
What is the difference between a statistician and a data scientist?
There is overlap. Statisticians focus on sound study design, inference and uncertainty; data scientists typically focus more on programming, large-scale data and machine learning. Many professionals combine both.
Is B.Sc Statistics enough to get a job?
It can lead to analyst roles, especially with programming skills and projects. Many core statistician, biostatistics and research roles prefer an M.Sc.
How can I join the Indian Statistical Service?
Through the UPSC Indian Economic Service / Indian Statistical Service exam, which requires a relevant degree in Statistics. Check the current UPSC notification for eligibility and age limits.
Can commerce students study statistics?
If you studied Mathematics in Class 12 (for example MEC), you can often take B.Sc Statistics or related degrees. Check each university’s requirements.
