When you dont have a control in an experiment , there is no basis of comparrison. A proper experiment , has an independent variable - purposefully changed - a dependent variable - measured result - a constant (that ones kind of obvious), and a control . When an experiment doesnt have a control , its also harder to draw conclusion. With a control , you have something to base your hypothesis on . If this doesnt help , try checking your textbook or search experimental design on Google or ask.com.
The controlled variable is the variable that is kept constant , meaning not changed, throughout the entire experiment.
A controlled variable is a variable left unchanged in an experiment
The variable that affects the dependent variable. It is the variable that you control.

controlled variable is something that is controlled by the independent variable
Manipulated Variable, Responding Variable, And Controlled Variable.
controlled variable is something that is controlled by the independent variable
A controlled variable is a setting where the dependent variable is not controlled by the independent variable. For example, if you were trying to measure the rate of movement in an organism in highly salty concentrations, a controlled variable would include the organism in an environment with no salt at all.
A Controlled Variable is a variable that will stay the same. An Uncontrolled Variable is a variable that stays at random during testing.
The controlled variable is the one that you chose to change while the dependant is the variable that changes because it is effected by the controlled variable
"Controlled Variable" or "Manipulated Variable"
manipulated variable
The independent variable.
constant variable
a control variable is a variable that needs to be controlled
The difference between a controlled variable and a variable is in their state. A controlled variable is something which is rigid and constant while a variable is liable to change and inconsistent.
