3. Investigation Design and Analysis
Aims and Hypotheses

4. Learning Objectives To describe the terms “aim” and “hypothesis”
To provide examples of aims for given experiments
To distinguish between a one-tailed (directional) and two-tailed (non-directional) hypothesis
To define independent and dependent variables

5. Aims
These reveal the intended purpose of the investigation – what do the researchers want to find out?

6. Hypothesis
This is a testable statement which predicts what is expected to happen in the research

7. The IV and DV
Independent variable (IV) – The thing manipulated by the experimenter
Dependent variable (DV) – The thing being measured
A scientist conducts an experiment to test the theory that a vitamin could extend a person’s life-expectancy…
The IV - the amount of vitamin that is given to the participants within the experiment
The DV - life span

8. Your Task Complete the Aims and Hypothesis page of your booklet
Extension – looking at the studies we’ve covered in Cognitive psychology so far, what would the aims and hypotheses be?

9. Two Tailed One Tailed Hypotheses
Non-directional – for example, the taking of vitamins will affect life expectancy
One Tailed
Directional – for example, participants who take more vitamins will live longer

10. Activity
In your groups/pairs decide a directional (one-tailed) for each of the experiments
Then redraft these to form a non-directional (two-tailed) for the same experiments
