When the chemist designs his experiment what should be the only independent variable?
temperature
What is the diffrence between dependent variable and independent variable?
the dependent variable changes with the independent variable. the independent variable only changes when changed by the experimenter. Time is usually an independent variable.
Is the independent variable the x value?
Not necessarily. It will be if it is the only independent variable in the system.
What is the variable you plot on the x-axis?
The x variable, of course! If there are only two variables then the independent variable, if one exists, should be plotted on the x-axis.
What does independent variable and dependent variable mean?
The independent variable is the variable that the scientist controls and can change in an experiment. There should be only one independent variable in an experiment; otherwise the cause-and-effect of the independent variable cannot be determined.The dependent variable is the variable that is affected by the independent variable.EXAMPLE:Students of the same age have been given different sleeping hours (the independent variable)The next day they are tested for their performance (the dependent variable).(Having students the same age is a third type of variable, called the constant variable or the control variable. It is deliberately kept the same to reduce any effects on the outcome.)
