About Mathematicians

Statisticians collect, analyze, interpret, and present data to help organizations and researchers draw valid conclusions and make sound decisions. They design studies and surveys to ensure data collection yields valid, representative results; apply statistical methods to analyze data; and communicate findings in ways that are accurate and accessible to decision-makers. In pharmaceutical and clinical research, biostatisticians design clinical trials, select appropriate primary endpoints, determine required sample sizes, manage randomization and blinding, perform pre-specified analyses, and produce statistical sections for FDA submissions. Government statisticians manage national surveys—employment, population, health, agriculture—applying complex sampling designs and weighting adjustments to produce estimates that represent the target population. Corporate statisticians apply methods ranging from regression and time series analysis to experimental design, quality control, and predictive modeling. Academic statisticians develop new statistical methods and publish research that advances the discipline. The master's degree in statistics or biostatistics is the standard entry credential; PhD programs prepare statisticians for independent research roles.
