"Faculty in the Department of Statistics engage in fundamental and multidisciplinary research to expand the scope of statistical methodology and its implementation in data intensive fields. Fundamental research in statistics is advancing methodology and its theoretical basis to accommodate new data structures and to generalize the scope of application. Data science research is expanding the range of statistical methods, data structures and algorithms, and software packages to address the massive amounts of data that can be collected and the challenges of drawing valid conclusions from it. Research in biostatistics includes methodology development and evaluation, design and analysis of health studies, and advanced applications in genomic research. Research in statistical methods for the social sciences is providing the framework for measurement, policy analysis and risk analysis.
Key drivers of modern research in statistics and data science are large scale high-dimensional data, network data, spatially and temporally correlated data, and large complex data bases." from Research Overview, Department of Statistics, University of Illinois at Urbana-Champaign
Books on statistics can be found in the Mathematics Library Stacks on the lower level shelved under call number range 519.5.
"Statistics, the science of collecting, analyzing, presenting, and interpreting data. Governmental needs for census data as well as information about a variety of economic activities provided much of the early impetus for the field of statistics. Currently the need to turn the large amounts of data available in many applied fields into useful information has stimulated both theoretical and practical developments in statistics." from "statistics."

"The mathematical study of the likelihood and probability of events occurring based on known information and inferred by taking a limited number of samples. Statistics plays an extremely important role in many aspects of economics and science, allowing educated guesses to be made with a minimum of expensive or difficult-to-obtain data. " from Statistics -- from Wolfram MathWorld.
"Statistics is the study of the collection, analysis, interpretation, presentation, and organization of data. In applying statistics to, e.g., a scientific, industrial, or social problem, it is conventional to begin with a statistical population or a statistical model process to be studied. Populations can be diverse topics such as "all people living in a country" or "every atom composing a crystal". Statistics deals with all aspects of data including the planning of data collection in terms of the design of surveys and experiments." From Wikipedia contributors. "Statistics."
