What is an independent variable, a dependent variable, and a controlled variable?

plz explain with details if u can. science is not my best subject. i always get the dependent variable and the independent variable mixed up, and then i end up not knowing what both of them mean. can somebody plx help me. really appreciate. You're the best!What is an independent variable, a dependent variable, and a controlled variable?
An independent variable a variable that is changed on purpose for the experiment.





A dependent variable is a variable that is caused by another variable [the independent variable].





A controlled variable is the variable that is kept the same throughout the entire experiment; it isn't changed or touched at all.What is an independent variable, a dependent variable, and a controlled variable?
First of al, isnt this the math section?


The independent variable is the part that actually changes what is done.


The dependent in what is effected by the change.


And a controlled variable doesn't make sense. Control means the part that does NOT change in an experiment whuke variable means the part that changes
Independent Variable =a variable in a functional relation whose value determines the value or values of other variables, as x in the relation y = 3x2.





Dependent Variable=a variable in a functional relation whose value is determined by the values assumed by other variables in the relation, as y in the relation y = 3x2.





controlled variable= ?
