  5. This is why you need that C in GCSE Maths…

  6. Learning objectives By the end of this section students will be able to: • Describe the aim of a study • Identify directional, non-directional and null hypotheses Icons key: For more detailed instructions, see the Getting Started presentation Flash activity (not editable) Teacher’s notes (in Notes Page) Accompanying worksheet Sound Video Web links Extension activity

  7. Aims and hypotheses What is the difference between the aim of a study and the experimental hypothesis? The hypothesis is a testable statement about what will happen. It is more precise than the aim. The hypothesis of Loftus & Palmer (1974) could have been: “participants that hear the word ‘smashed’ will estimate that the cars were travelling faster than participants that hear ‘contacted’”. The aim of a study describes its purpose. For example, the aim of Loftus & Palmer (1974) could have been: “to investigate whether leading questions can alter people’s memory of a car crash”.

  8. Task • Complete page 7 of your booklet. • You need to write 5 hypotheses using the key words given. • Make sure that they are ‘operationalised’. Do you remember that word from the taster session?

  9. Writing hypotheses There are two types of experimental hypothesis: directional and non-directional. There is also the nullhypothesis. A directional hypothesispredicts the direction of any differences in the way people behave. For example, a directional hypothesis would predict that participants who eat chocolate before a test will achieve a significantly higher score than those participants who do not.

  10. Writing hypotheses A non-directional hypothesispredicts a difference in the way people behave but not which direction this will be in. For example,a non-directional hypothesis would predict there will be a significant difference in participants’ test scores depending on whether they eat chocolate before the test or not. A null hypothesis predicts that the independent variable will have no effect on the dependent variable. For example, a null hypothesis would predict thatthere will be no significant difference in participants test scores depending on whether they eat chocolate or not.

  11. Identify the hypothesis

  12. Task • Complete page 8 of your booklet. • You need to decide whether the hypotheses are directional or non-directional. • Read the box about operationalising at the bottom of the page. Extension: Fill in your key terms glossary.
