Data analysis can be performed for quantitative and qualitative data sets in different industries. 

Typically, a statistician and mathematician applies theories and formulas to solve practical challenges in several fields, such as medical, science, engineering and business. 

When starting a project, these experts can help define what kind of data is required in order to answer a specific question, what is the sample size required and what sampling method is the most appropriate. 

They can participate in the design of experiments, questionnaires, opinion polls and surveys, in addition to creating mathematical models for data analysis.

After data collection, they use specific software to perform comprehensive analyses, including trends, associations, limitations and validity. The findings are presented as tables, charts, graphs and reports and their interpretation leads to the discussion and conclusions. 

Statisticians tend to work in healthcare, research and development, educational institutions and government. They usually work in close collaboration with other professionals, such as scientists, engineers, pharmacists, chemists, physicians and other healthcare workers.

In business, statistics play a crucial role in quality control, product improvement and development.

In some industries, statistics can be used as a tool to predict certain traits through calculation of probabilities. Modelling can be necessary in order to provide information on product liability.

In the world of IT, cyber security programs can require statistical approaches when there is electronic data and potential threats involved. 

Forecasting of data can become a necessity for projects related to economics, risk management and corporate governance. Predictions are an important part of politics, which can anticipate an election result for instance.

In production, engines can be tested during rounds of experiments run according to statistical principles for example. 

In scientific projects, statistics is vital from planning to execution, from analysis to publication. With the rise in evidence-based guidelines for medicine and healthcare-related professions, statisticians who have experience in systematic review and meta-analysis can be really useful. During the development of new drugs, safety and effectiveness are determined according to the interpretation of data collected through clinical trials.

Even legal cases might call for probability and statistics, particularly when dealing with insurance claims.

Different projects might require specialized expertise:

• Finance statistics expert
• Environmental statistics expert
• Business statistics expert
• Medical statistics expert

This profession basically deals with the transformation of data into information, which can be applied to practical tools and solutions.
