A coefficient is an integer that is multiplied with the variable of a single term or the terms of a polynomial. Learn all about the coefficient of a variable in this article along with examples and practice questions.
1.A number or symbol multiplied with a variable or an unknown quantity in an algebraic term, as 4 in the term 4x,orxin the termx(a+b). 2.A numerical measure of a physical or chemical property that is constant for a system under specified conditions, such as the coefficient of friction...
To get the answer in percentage terms, we can multiply the resultant number by 100. We also have a mathematical formula to compute the CV. And this formula is: In the formula, Xi is the ithrandom variable, X is the mean of the data series, and N is the number of variables. ...
An algebraic expression may consist of one or more terms. The coefficient of each term is the numerical factor of the variable. For example, in the term {eq}6x {/eq}, the coefficient is {eq}6 {/eq} and the variable is {eq}x. {/eq} ...
So, the special number 3 is called the coefficient of the term 3x. What is a simple definition of coefficient? A coefficient in mathematics is a numerical factor that multiplies a variable. The variable represents an unknown, and the number associated with it is termed the coefficient. When ...
Coefficient of Variation (in financial terms) is also referred to as volatility of the investment. Naturally, the investment having a lower degree of volatility is the safer one. Thus, in the investment scenario, the formula of the coefficient of variation should be, CV = Volatility / Expected...
A statistic which indicates the strength of fit between two variables implied by a particular value of the sample correlation coefficientr. Designated byr2. McGraw-Hill Dictionary of Scientific & Technical Terms, 6E, Copyright © 2003 by The McGraw-Hill Companies, Inc. ...
5.1 in terms of the strain gradient quantities. This task is not as formidable as it might appear because the coefficients of the different order terms can be evaluated one set at a time. That is to say, the constant coefficients are evaluated as a separate set, the first-order ...
Several other terms are synonymous with COV, including the variation coefficient, unitized risk, and relative standard deviation. The Zero Disadvantage Suppose the mean of a sample population is zero. In other words, the sum of all values (above and below zero) equals zero. Under this circumstan...
In finance, the coefficient of variation allows investors to determine how muchvolatility, or risk, is assumed in comparison to the amount of return expected from investments. Ideally, if the coefficient of variation formula should result in a lower ratio of thestandard deviationto mean return, th...
