For example, all we can say is that 2 individuals are different in terms of variable A (e.g., they are of different race), but we cannot say which one "has more" of the quality represented by the variable. Typical examples of nominal variables are gender, race, color, city, etc. b. In probability theory and statistics, the Normal Distribution, also called the Gaussian Distribution, is the most significant continuous probability distribution. Sometimes it is also called a bell curve. A large number of random variables are either nearly or exactly represented by the normal distribution, in every physical science and economics.For decades, school architects have obsessed with creating optimized spaces, fiddling with furniture, ventilation, lighting, acoustics, ergonomics and sanitation.

In statistics, the term population refers to all members of a set that will be studied. A population might consist of people (as in, for example, a drug trial), but it may not. 1.1: Basic Definitions and Concepts. Statistics is a study of data: describing properties of data (descriptive statistics) and drawing conclusions about a population based on information in a sample (inferential statistics).
