In an algebraic expression (or equation), a coefficient is the numerical multiplier for a term. If the coefficient is, itself, a variable, then it is a parameter.
For example, the equation of a straight line in 2-d is
y = mx + c
where
x and y are the coordinate variables,
m is the parameter which defines the slope, and
c is the parameter which defines the y-intercept.
Different values of m will give a set of lines with the same intercept, whereas different values of c will give a set of lines with the slope. Varying both, together, will generate all possible lines.
By contrast, in the equation y = 2x + 5, 2 is the coefficient of x and 5 is the constant [coefficient]. They are specific values of the parameter whic define a specific line.

What is the difference between factors and coefficient?
The difference between factors and coefficient is very distinct. A factor is a quantity which is multiplied with another to give a particular number as the result. A coefficient on the other hand is a multiplier that measures property.
Relationship between coefficient lift and coefficient drag?
For cylinders coefficient of lift is approximately half of coefficient of drag while they are equal for Aerofoils.
What is multiple correlation coefficient and partial correlation coefficient?
partial correlation is the relation between two variable after controlling for other variables and multiple correlation is correlation between dependent and group of independent variables.
Spearman's rank correlation coefficient for grouped data?
Although Spearman's rank correlation coefficient puts a numerical value between the linear association between two variables, it can only be used for data that has not been grouped.
