A Statistician is someone who uses mathematical techniques to analyze and interpret data and draw conclusions. Statisticians collect, analyse and interpret numerical data across a broad spectrum of industries and topics.

They can work in areas as diverse as analysing medical data to determine where outbreaks of disease began and how they are likely to spread, through to compiling a cricketer's batting and/or bowling figures.

Statisticians design data collection methodologies, including sample size, location, questions to be asked and data collection method. Once the data has been collected they can examine it for patterns and trends, which can suggest reasons behind past events and sometimes also predict likely future happenings.

Statisticain determine the questions or problems to be addressed, Decide what data is needed to answer questions or problems and Determine methods for finding or collecting data. After that they Design surveys or experiments or opinion polls to collect data and .Collect data or train others to do so. They Analyze and interpret data and Report conclusions from their analyses Statisticians design surveys, experiments, and opinion polls to collect data. Some surveys, such as the national census, include data from nearly everyone.

Statisticians develop survey questionnaires or reporting forms for collecting the data they need. Statisticians analyze the data that is collected. In their analyses, they calculate averages, reliability, and other specifics. They also choose and conduct tests to find out the data’s reliability and validity.

They explain the limitations of the data to prevent inaccurate conclusions from being drawn, and they identify trends and relationships. Statisticians use computers with specialized statistical software to analyze data. Some help to create new statistical software packages to analyze data more accurately and efficiently.

Work Environment

• About a third of statisticians work for the government, mostly at the federal level. They are sometimes called mathematical statisticians. These workers develop advanced statistical models for several purposes, such as filling in gaps from non-responses to surveys. They usually work as part of a team, which may include scientists, computer programmers, research specialists and administrative staff. Many statisticians work for private businesses, such as pharmaceutical and insurance companies, and often work in teams with other professionals. For example, in pharmaceutical companies, statisticians may work with scientists to test drugs for government approval. Statisticians usually work standard business hours, though overtime may be required when working to tight deadlines.

Entry Level Education

• Bachelor's or Graduate Degree in Statistics or related area.
