Design Aspect 1
Defining and Selecting Variables
-
State the research question clearly under the heading “Research question”. It should be phrased in the form “how is y dependant on x”.
-
If the topic is not obvious it is wise to write a paragraph introducing the topic before you state the research question.Identify and list the independent variable (this is the one you are changing, x) and dependent variable (the one that changes, y).
-
Identify and list the controlled variables. These are all the other quantities that you could change but that are being kept constant.
-
You will not be graded on writing a hypothesis but it is good practice to say what you expect to happen.
