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...
The meaning of COEFFICIENT is any of the factors of a product considered in relation to a specific factor; especially : a constant factor of a term as distinguished from a variable. How to use coefficient in a sentence.
multiple correlation coefficient- an estimate of the combined influence of two or more variables on the observed (dependent) variable biserial correlation,biserial correlation coefficient- a correlation coefficient in which one variable is many-valued and the other is dichotomous ...

In a mathematical modeling setting, the CV is calculated as theroot mean squared error (RMSE)divided by the mean of thedependent variable[1]. The RMSE is a measure of difference between the predicted and observed values. The coefficient of variation is particularly useful when comparing results ...
The coefficient of variation is a frequently used term in statistics. In statistics, one cannot take things at face value. The data on hand could reveal one thing, whereas a more in-depth examination could end up revealing something else. Hence, this definition of statistics has become famous...
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} ...
aThis non dimensional coefficient describes whether the dispersion relative to the central value of a certain random variable is large or small. It is defined as the ratio of the standard deviation over the mean value of the random variable, i.e. 这个非尺寸系数描述分散作用相对某一随机变量的...
and it is a useful statistic for comparing the degree of variation from one data series to another, even if the means are drastically different from one another.
