What is a Statistician?

Duties Performed by Professional Statisticians
A professional statistician has a wide range of skills and capabilities. The following are common standards sought among statistician job requirements.
A statistician needs to be comfortable interviewing individuals or groups, either to prepare for a study or in the context of the study itself. The interviews may be held with the decision-makers and stakeholders to ensure a thorough understanding of the business/research question. Interviews might also be conducted with those participating in the study for further understanding and to elicit additional insights.
It is critical for a statistician to employ the most appropriate design to answer a business/research question, which is typically customized to a particular question. This tends to involve controlling for extraneous variables that may affect the results beyond those put in play by the researcher. The statistician also makes the determination if the question requires a longitudinal study or if a retrospective study may be more beneficial.
Data collection involves determining who or what comprises the target sample and how to best collect it to minimize potential bias (and therefore error). The statistician needs to calculate the appropriate size of a sample to ensure that any test conducted is sufficiently powerful to detect a result. Data needs to be properly prepared for analysis; this frequently involves determining reasons for missing information and how to best resolve any other data abnormalities.
Analysis of data takes a variety of forms as dictated by both the business/research question and the study design. A statistician might perform a test to determine:
- Group differences; for example, did an experimental group have a statistically significant health improvement over a control group?
- Dimension reduction; taking a large set of responses and reducing them to a more manageable list of factors.
- Prediction analysis; particularly in marketing, when discerning what products or services a company’s customers may want.
- Process analysis and quality control; to reduce waste and improve efficiency in manufacturing.
Statisticians frequently report their results to non-technical audiences; therefore, they must be able to do so in ways that are accurate and straightforward. Most statistician job requirements include the ability to graph results and create visual presentations. Statisticians may do more than report to the decision-makers or stakeholders – they may also disseminate their findings in professional journals or at conferences.
