Investigation Design and Analysis Aims and Hypotheses

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

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

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

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

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?

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

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
