Statistics, the science of collecting, analyzing, presenting, and interpreting data. 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.
Statistics is a branch of mathematics. It involves gathering information, summarizing it, and deciding what it means. The numbers that result from this work are also called statistics. They can help to predict such things as the weather and how sports teams will perform.
Probability and statistics, the branches of mathematics concerned with the laws governing random events, including the collection, analysis, interpretation, and display of numerical data. Learn more about the history of probability and statistics in this article.
Deforestation, clearing or thinning of forests by humans to make the land available for other uses. Deforestation is a major driver of terrestrial habitat loss and habitat fragmentation and contributes to global warming. Learn about historical and modern deforestation and its effects.
Percentage, a relative value indicating hundredth parts of any quantity. One percent is a hundredth part; thus, 100 percent represents the entirety and 200 percent specifies twice the given quantity. Percentages can be used to calculate profit and loss in business and to express probability.
This article provides an overview of the scientific background related to the subject of global warming. It considers the causes of rising near-surface air temperatures, the influencing factors, the process of climate research and forecasting, and the possible ecological and social impacts of rising temperatures.
Matrix, a set of numbers arranged in rows and columns so as to form a rectangular array. The numbers are called the elements, or entries, of the matrix. Matrices have wide applications in engineering, physics, economics, and statistics as well as in various branches of mathematics.
Introduction. Anyone who watches television, browses the Internet, or reads books, newspapers, and magazines cannot help but be aware of statistics. The term statistics is used in two different ways. When used in the plural, it refers to numerical data.
Racism, the belief that humans may be divided into separate and exclusive biological entities called ’races’; that there is a causal link between inherited physical traits and traits of personality, intellect, morality, and other cultural and behavioral features; and that some races are innately superior to others.
Probability theory, a branch of mathematics concerned with the analysis of random phenomena. The outcome of a random event cannot be determined before it occurs, but it may be any one of several possible outcomes. The actual outcome is considered to be determined by chance.
