Planting trees in Europe could lead to more rainfall

A combined team of researchers from ETH Zurich, Institute for Atmospheric and Climate Science and Newcastle University, has found via statistical analysis and modeling that rainfall in Europe could be increased by planting ...

Black holes help with star birth

Research combining systematic observations with cosmological simulations has found that, surprisingly, black holes can help certain galaxies form new stars. On scales of galaxies, the role of supermassive black holes for ...

Two biodiversity refugia identified in the Eastern Bering Sea

Scientists from Hokkaido University have used species survey and climate data to identify two marine biodiversity refugia in the Eastern Bering Sea—regions where species richness, community stability and climate stability ...

Study finds link between empathy and care for the environment

A study conducted by a team of researchers fromNanyang Technological University, Singapore (NTU Singapore) has found that Singaporeans who score high levels of empathy choose to prioritize the environment over the convenience ...

New dataset opens Estonian soil information for versatile use

A comprehensive database of Estonian soils and a map application has been completed in cooperation with researchers of the University of Tartu and the Estonian University of Life Sciences. The database makes Estonian soil ...

A benchmark for single-electron circuits

Manipulating individual electrons with the goal of employing quantum effects offers new possibilities and greater precision in electronics. However, these single-electron circuits are governed by the laws of quantum mechanics, ...

Statistics

Statistics is a mathematical science pertaining to the collection, analysis, interpretation or explanation, and presentation of data. Statisticians improve the quality of data with the design of experiments and survey sampling. Statistics also provides tools for prediction and forecasting using data and statistical models. Statistics is applicable to a wide variety of academic disciplines, including natural and social sciences, government, and business.

Statistical methods can be used to summarize or describe a collection of data; this is called descriptive statistics. This is useful in research, when communicating the results of experiments. In addition, patterns in the data may be modeled in a way that accounts for randomness and uncertainty in the observations, and are then used to draw inferences about the process or population being studied; this is called inferential statistics. Inference is a vital element of scientific advance, since it provides a prediction (based in data) for where a theory logically leads. To further prove the guiding theory, these predictions are tested as well, as part of the scientific method. If the inference holds true, then the descriptive statistics of the new data increase the soundness of that hypothesis. Descriptive statistics and inferential statistics (a.k.a., predictive statistics) together comprise applied statistics.

There is also a discipline called mathematical statistics, which is concerned with the theoretical basis of the subject.

The word statistics can either be singular or plural. In its singular form, statistics refers to the mathematical science discussed in this article. In its plural form, statistics is the plural of the word statistic, which refers to a quantity (such as a mean) calculated from a set of data.
