Definition von normal curve im Englisch Englisch wörterbuch
A graphical interpretation of a population that is 'bell shaped' as it has the highest frequency in the middle and this frequency diminishes the farther you get from the center on either end
A bell-shaped graph representing a hypothetical frequency distribution for a given characteristic
a mathematical model that show the relationship between tow variables--in our case, test scores and the proportion of students
A bell-shaped, symmetrical relative frequency curve We will present the exact equation that gives this curve in Chapter 5 (page 47)
The normal curve is the familiar "bell curve: ," illustrated on this page The mathematical expression for the normal curve is y = (2×pi)-½e-x2/2, where pi is the ratio of the circumference of a circle to its diameter (3 14159265 ), and e is the base of the natural logarithm (2 71828 ) The normal curve is symmetric around the point x=0, and positive for every value of x The area under the normal curve is unity, and the SD of the normal curve, suitably defined, is also unity Many (but not most) histograms, converted into standard units, approximately follow the normal curve

A curve of a probability distribution It is also sometimes called a bell shaped curve The curve is completely specified by its mean and standard deviation
A mathematically derived curve depicting the theoretical probability or distribution of a given variable (such as a physical trait or test score) in the general population
