Question

In this experiment, the blank
was intentionally manipulated. This was the independent variable.
The dependent variable measured was the blank

Answer 1

Here we need to identify the independent and dependent variables in an experiment.

Sadly, we have no information about the experiment, so we need to give a general answer.

In an experiment, we can define 3 types of variables.

• Independent variable: Is the thing that we can change as we do the experiment.
• Dependent variable: Is a variable that responds to the changes in the independent variable, this is the thing we observe/study.
• Fixed/controlled variables: Are a group of other variables that also affect the dependent variable. Because we want to study the relation between the dependent variable and the independent variable, all of these other things that also affect the dependent variable must remain fixed in the experiment.

Now that you know this you could guess which one is the independent and which one is the dependent.

Just to give an example, suppose that your experiment is "How hot a piece of steel gets in an oven as a function of the time it is inside".

The time, the thing that you control, is the independent variable.

The temperature of the piece of steel, the thing you measure, is the dependent variable.

The controlled variables are things like the type of oven, the temperature at which the oven is, the position of the piece of steel inside the oven, etc.
