if coefficient of skewness is zero then distribution is symmetric or zero skewed.
The numerical value that comes before the variable or, if none, the coefficient is 1.The numerical value that comes before the variable or, if none, the coefficient is 1.The numerical value that comes before the variable or, if none, the coefficient is 1.The numerical value that comes before the variable or, if none, the coefficient is 1.
It depends on what the underlying distribution is and which coefficient you want to calculate.
A coefficient in front of the absolute value sign means to multiply that coefficient by the absolute value in the problem. For instance 3*ABS(-3) = 3*3 = 9.
It's the value of a variable, eg 2 is the coefficient of n in the expression 2n
