A control variable is a variable that is held constant in a research analysis.
Because its the group for which the idependent variable is help constand in a statistical study.
a control variable is a variable that needs to be controlled
An independent variable does not change. It is independent of everything else In research, there needs to be a dependant variable.
The dependent variable is the variable that the researcher does not control. The researcher will change one variable called the independent variable (ex. temperature, amount of sunlight, amount of food, etc.) and then observe the corresponding dependent variable (ex. reaction of organism, amount of plant growth, swimming speed, etc.)
An independent variable is when you do not control what happens In an experiment,however; a dependent variable is when you actually control the experiment,

There are not any similarities between a control and a variable. However, a Control Variable, is a variable.
An independent variable does not change. It is independent of everything else In research, there needs to be a dependant variable.

You can control it that's why its called control variable.
what is the difference between a variable and a control
The dependent variable is the variable that the researcher does not control. The researcher will change one variable called the independent variable (ex. temperature, amount of sunlight, amount of food, etc.) and then observe the corresponding dependent variable (ex. reaction of organism, amount of plant growth, swimming speed, etc.)

who to control one variable at time
