Question 23

Dependent Variable

Answer 23

A dependent variable is the variable being tested in a scientific experiment. The dependent variable is ‘dependent’ on the independent variable.When you take data in an experiment, the dependent variable is the one being measured.

Question 24

Independent Variable

Answer 24

An independent variable is exactly what it sounds like. It is a variable that stands alone and isn’t changed by the other variables you are trying to measure.

Question 25

Constant Variable

Answer 25

It is the control variable, also known as the constant variable. As the name suggests, it is the variable that the scientist wants to remain the same. Often, there is more than one control or constant variable in a scientific experiment.

Question 26

Hypothesis

Answer 26

A hypothesis is an assumption, an idea that is proposed for the sake of argument so that it can be tested to see if it might be true. In the scientific method, the hypothesis is constructed before any applicable research has been done, apart from a basic background review.
