Any variable can be declared as the independent variable, then the other would be the dependent variable. However, it is quite common to arbitrarily define y as the dependent variable - a variable that depends on x.
I define an variable by saying x- an value
Take the expression y = f(x) where f is a function relating y in terms of x. x is the input - the independant variable. y is the output - the dependant variable because it's value depends on x.
State what the variable represents in the equation.
Declaration is a promise: 'I will define (or has defined) this variable/function somewhere else'.

The gradient of a curve is the rate of change in the dependent variable relative to the independent variable.
A dependent (responding) variable is a condition that can change as the result of an independent variable's alteration. It can also be referred to as an effect. Every well-designed experiment has three kinds of variables. 1) Control variables, which are the same for each stage of the experiment. 2) Independent (manipulated) variables, which represent what is being changed by experimenters. 3) Dependent (responding) variables, which respond to the change and ideally are the direct result of the change in the independent (manipulated) variables.
Independent variables answer the question "What do I change?"Dependent variables answer the question "What do I observe?"Controlled variables answer the question "What do I keep the same?"

describes how to measure a variable or define a term. right out of my science book

They define a variable by saying n equals some value.
To operationalize a dependent variable, you need to clearly define how it will be measured in your study. This involves establishing specific criteria or indicators that represent the construct of interest, such as using a survey question, observation, or experimental outcome to quantify the variable. It is essential to ensure that your operationalization accurately captures the concept you are studying and allows for consistent and reliable measurement.
