Statisticians are responsible for collecting, analyzing and interpreting numerical data. Its results help other professionals make informed decisions, create company policies, and understand different aspects of modern life.
Many are tasked with working in central or local government departments, using statistical information to help create policy and advise the public.
Statisticians work in departments of the public administration and associated agencies.
They provide an information and advisory service for the government and parliament. This helps ministers to develop and implement policies, for example in health or justice, and assess their impact on the public.
Government statisticians can, for example, examine the functioning and effectiveness of the public health system in terms of waiting lists, hospitals, staffing, and ambulance response times.
Apart from the civil service, the largest employer of statisticians is the pharmaceutical industry. There, statisticians are dedicated to designing and analyzing experiments to evaluate the effects of drugs and to test their safety.
They can be involved in all stages of drug development, from designing experiments to find useful biological compounds, to clinical trials conducted before and after the drug is available to the public.
Statisticians also play a key role in medical research in a broader sense, for example:
- In the control of heart disease.
- In establishing the causes of the disease or the factors associated with the disease.
- In the prevention of deaths or illnesses.
- In the evaluation of treatments.
Since there can be great variation in the factors that cause disease, and in people’s responses to treatment, statisticians must develop methods to take these elements into account, collecting and explaining the patterns that emerge.
They also design, implement, and evaluate clinical trials. Some studies may take only a few months to complete, while in others it may take years before the results are significant. Statisticians then have to write reports and articles for later publication, and they can present the results at conferences within their country or abroad.
Statisticians are working more and more in biometrics, for example, in the investigation of the possibilities of inheriting a certain disease, or in the verification of the functioning of new varieties of crops.
In business and industry, statisticians work on market research. They are dedicated to predicting demand to help target products to a particular market.
They also play a vital role in quality management and production. Your information can help streamline processes and minimize business waste and reduce industrial pollution.
Statisticians play an important role in the economy, business, and industry. For example, they also play a role in calculating risks (probability of an event occurring) in areas such as pensions and life insurance.
They also work for banks, in credit risk assessment, and for investment firms, in monitoring and analyzing the stock market. Insurance companies employ play a role in producing risk models and life expectancy statistics.
There are also statisticians in areas such as journalism, teaching, and university teaching and research.
While statisticians may be self-employed as consultants, they almost always work as a team, collecting and analyzing data from a wide variety of sources and communicating with other professionals does not play a role.
They should always think carefully about the best methods they can use to collect and interpret the data in each case. For example, sometimes bias can occur unintentionally if an important factor has been left out, and this can distort the results.
