Minimum qualifications

Master’s degree is generally required to work as statistician. However, this requirement may differ in some countries.

ISCO skill level

ISCO skill level is defined as a function of the complexity and range of tasks and duties to be performed in an occupation. It is measured on a scale from 1 to 4, with 1 the lowest level and 4 the highest, by considering:

  • the nature of the work performed in an occupation in relation to the characteristic tasks and duties
  • the level of formal education required for competent performance of the tasks and duties involved and
  • the amount of informal on-the-job training and/or previous experience in a related occupation required for competent performance of these tasks and duties.

Statistician is a Skill level 4 occupation.

Essential knowledge and skills

Essential knowledge

This knowledge should be acquired through learning to fulfill the role of statistician.

Mathematics: Mathematics is the study of topics such as quantity, structure, space, and change. It involves the identification of patterns and formulating new conjectures based on them. Mathematicians strive to prove the truth or falsity of these conjectures. There are many fields of mathematics, some of which are widely used for practical applications.
Statistics: The study of statistical theory, methods and practices such as collection, organisation, analysis, interpretation and presentation of data. It deals with all aspects of data including the planning of data collection in terms of the design of surveys and experiments in order to forecast and plan work-related activities.
Statistical analysis system software: Specific software system (SAS) used for advanced analytics, business intelligence, data management, and predictive analytics.
Data quality assessment: The process of revealing data issues using ​quality indicators, measures and metrics in order to plan data cleansing and data enrichment strategies according to data quality criteria.
Scientific research methodology: The theoretical methodology used in scientific research involving doing background research, constructing an hypothesis, testing it, analysing data and concluding the results.

Essential skills and competences

These skills are necessary for the role of statistician.

Identify statistical patterns: Analyse statistical data in order to find patterns and trends in the data or between variables.
Gather data: Extract exportable data from multiple sources.
Perform data analysis: Collect data and statistics to test and evaluate in order to generate assertions and pattern predictions, with the aim of discovering useful information in a decision-making process.
Execute analytical mathematical calculations: Apply mathematical methods and make use of calculation technologies in order to perform analyses and devise solutions to specific problems.
Apply statistical analysis techniques: Use models (descriptive or inferential statistics) and techniques (data mining or machine learning) for statistical analysis and ICT tools to analyse data, uncover correlations and forecast trends.
Think analytically: Produce thoughts using logic and reasoning in order to identify the strengths and weaknesses of alternative solutions, conclusions or approaches to problems.
Apply scientific methods: Apply scientific methods and techniques to investigate phenomena, by acquiring new knowledge or correcting and integrating previous knowledge.
Conduct quantitative research: Execute a systematic empirical investigation of observable phenomena via statistical, mathematical or computational techniques.
Process data: Enter information into a data storage and data retrieval system via processes such as scanning, manual keying or electronic data transfer in order to process large amounts of data.

Optional knowledge and skills

Optional knowledge

This knowledge is sometimes, but not always, required for the role of statistician. However, mastering this knowledge allows you to have more opportunities for career development.

Biometrics: The science that statistically analyses human characteristics such as retina, voice or DNA for identification purposes.
Algorithms: The self-contained step-by-step sets of operations that carry out calculations, data processing and automated reasoning, usually to solve problems.
Market research: The processes, techniques, and purposes comprised in the first step for developing marketing strategies such as the collection of information about customers and the definition of segments and targets.
Opinion poll: The inquiry of the opinion of the public, or at least of a representative sample, about a determined subject.
Information confidentiality: The mechanisms and regulations which allow for selective access control and guarantee that only authorised parties (people, processes, systems and devices) have access to data, the way to comply with confidential information and the risks of non-compliance.
Demography: The scientific field of study that deals with studying the size, structure, and distribution of the human population, and its geographical and temporal changes.
Set theory: The subdiscipline of mathematical logic that studies the properties of well-determined sets of objects, relevant to mathematics.

Optional skills and competences

These skills and competences are sometimes, but not always, required for the role of statistician. However, mastering these skills and competences allows you to have more opportunities for career development.

Write research proposals: Synthetise and write proposals aiming to solve research problems. Draft the proposal baseline and objectives, the estimated budget, risks and impact. Document the advances and new developments on the relevant subject and field of study.
Prepare lesson content: Prepare content to be taught in class in accordance with curriculum objectives by drafting exercises, researching up-to-date examples etc.
Manage database: Apply database design schemes and models, define data dependencies, use query languages and database management systems (DBMS) to develop and manage databases.
Build predictive models: Predictive modelling is the process by which a model is created or chosen to try to best predict the probability of an outcome.
Analyse big data: Collect and evaluate numerical data in large quantities, especially for the purpose of identifying patterns between the data.
Develop financial statistics reports: Create financial and statistical reports based on collected data which are to be presented to managing bodies of an organisation.
Perform scientific research: Gain, correct or improve knowledge about phenomena by using scientific methods and techniques, based on empirical or measurable observations.
Conduct public surveys: Conduct the procedures of a public survey from the initial formulation and compilation of the questions, identifying the target audience, managing the survey method and operations, managing the processing of acquired data, and analysing the results.
Advise on financial matters: Consult, advise, and propose solutions with regards to financial management such as acquiring new assets, incurring in investments, and tax efficiency methods.
Develop scientific theories: Formulate scientific theories based on empirical observations, gathered data and theories of other scientists.
Develop statistical software: Participate in the various development stages of computer programs for econometric and statistical analysis, such as research, new product development, prototyping, and maintenance.
Carry out statistical forecasts: Undertake a systematic statistical examination of data representing past observed behaviour of the system to be forecast, including observations of useful predictors outside the system.
Write scientific papers: Present the hypothesis, findings, and conclusions of your scientific research in your field of expertise in a professional publication.
Deliver visual presentation of data: Create visual representations of data such as charts or diagrams for easier understanding.
Present reports: Display results, statistics and conclusions to an audience in a transparent and straightforward way.
Provide lesson materials: Ensure that the necessary materials for teaching a class, such as visual aids, are prepared, up-to-date, and present in the instruction space.
