Lärarutbildning: Utbildning. Equations and what they mean. Matematik. Medan naturvetenskapen studerar entiteter i tid och rum är det inte uppenbart att samma är sant för de objekt som studeras i matematik.[7] Vidare skiljer sig metoderna för undersökning åt: naturvetenskapen tenderar att använda metoder av induktion och matematiken metoder av deduktion.[7] Av bland annat nämnda skäl väcker matematik ontologiska och kunskapsteoretiska frågor skilda från vetenskapsteorin.[7] Dessa frågor behandlas i matematikfilosofi.[7]

Lay - Linear Algebra. Vi Hart: Mathemusician. Category Theory. First published Fri Dec 6, 1996; substantive revision Fri Apr 26, 2013 Category theory has come to occupy a central position in contemporary mathematics and theoretical computer science, and is also applied to mathematical physics.

Roughly, it is a general mathematical theory of structures and of systems of structures. As category theory is still evolving, its functions are correspondingly developing, expanding and multiplying. At minimum, it is a powerful language, or conceptual framework, allowing us to see the universal components of a family of structures of a given kind, and how structures of different kinds are interrelated. Divisibility by Seven. Everyone learns in grade school some simple tests for divisibility by small numbers such as 2, 3, 5, and 9. But far less well-known are some simple divisibility tests for the number 7. Here are a couple: Test #1.

Psychology. Psychology is an academic and applied discipline that involves the scientific study of mental functions and behaviors.[1][2] Psychology has the immediate goal of understanding individuals and groups by both establishing general principles and researching specific cases,[3][4] and by many accounts it ultimately aims to benefit society.[5][6] In this field, a professional practitioner or researcher is called a psychologist and can be classified as a social, behavioral, or cognitive scientist.

Psychologists attempt to understand the role of mental functions in individual and social behavior, while also exploring the physiological and biological processes that underlie cognitive functions and behaviors. While psychological knowledge is often applied to the assessment and treatment of mental health problems, it is also directed towards understanding and solving problems in many different spheres of human activity. Myers-Briggs. Linköpings universitet. Portal:Statistics - Wiki. Statistics. Statistics is the study of the collection, organization, analysis, interpretation and presentation of data.[1] It deals with all aspects of data including the planning of data collection in terms of the design of surveys and experiments.[1] When analyzing data, it is possible to use one or both of statistics methodologies: descriptive and inferential statistics in the analysis data.[2] Scope[edit]

Probability and Statistics Cookbook. The cookbook contains a succinct representation of various topics in probability theory and statistics.

It provides a comprehensive reference reduced to the mathematical essence, rather than aiming for elaborate explanations.

Use in statistical analysis[edit] Descriptive statistics provides simple summaries about the sample and about the observations that have been made.

Such summaries may be either quantitative, i.e. summary statistics, or visual, i.e. simple-to-understand graphs. StaLin - Sektionen för statistikstuderande vid Linköpings Universitet.
