a variable can be defined as a quantity in an equation which explains the behaviour of the given function
operational definition of a manipulated variable
operational definition of a manipulated variable
describes how to measure a variable or define a term. right out of my science book
A variable is an unknown number represented by a letter
An independent variable is a factor that is changed by the controller of the experiment.
The operational definition of the dependent variable in an experiment specifies how the variable will be measured or observed. It defines the specific outcome or response that is being assessed as a result of manipulating the independent variable.
The question should be what is the variable in the following expression? (n + 5) The answer: (n) represents the variable. See: Variable(English definition) then look up the Math/Algebra definition.
Operational definition. :)
variable definition means to declare the variable with its value. for example:- int i=10; this statement is a combination of declaration of integer i and assign its value to it,so it is a definition statement Note: assigning a value is not essential.
visithttp:/www.statisticssolutions.com/moderator-variable. it gives good definition of moderator variable
A variable that stay the same during a science experiment
The Variable Rate is the rate at which a number changes
