IDE is available, for free, at When we first, in the 1990s, became acquainted with Hubert Hohn and his wonderful interactive illustrations we knew immediately that he had found a real key to making our subject (and many others) come alive--not only for students, but for ourselves and our faculty colleagues.

Hohn is a master educator. Ordinary Differential Equations - Resources. The sources below are among some of the best locations of sites dedicated to ordinary differential equations, online and on the computer.

Paired Sample t-test A paired sample t-test is used to determine whether there is a significant difference between the average values of the same measurement made under two different conditions.

Both measurements are made on each unit in a sample, and the test is based on the paired differences between these two values. The usual null hypothesis is that the difference in the mean values is zero. For example, the yield of two strains of barley is measured in successive years in twenty different plots of agricultural land (the units) to investigate whether one crop gives a significantly greater yield than the other, on average.

Usando a notação R[x] para a raiz quadrada de x>0, a média geométrica entre x e y, é definida como a raiz quadrada do produto de x por y, isto é: Maths online. GCSE Bitesize - Maths.

Tópico: [Distribuição qui-quadrado] A distribuição qui-quadrado é uma distribuição contínua de grande importância para a inferência estatística.

É uma distribuição que surge no contexto de somas de quadrados de variáveis aleatórias com distribuição normal. Uma variável qui-quadrado aparece em numerosas situações da inferência estatística: A distribuição qui-quadrado foi inicialmente proposta por Abbé em e,posteriormente, tratada por Karl Pearson em .

Welcome to the Wikibook of Statistics Statistics - Area of applied mathematics concerned with the data collection, analysis, interpretation and presentation.

Statistics is used in almost every field of research: the discovery of the Higgs particle, social sciences, climate research,...

Breaking down the barriers between physics, chemistry and biology and the so-called soft sciences of psychology, sociology, economics, and anthropology, this text explores the universal physical and mathematical principles that govern the emergence of complex systems from simple components.
