- The Experimental Method
- Ethical Issues
- Never use anyone under the age of 16 as a participant (or anyone hat is described as vulnerable in any way)
- Always obtain informed consent from all participants, telling them what they will be expected to do and allowing them to refuse to take part
- Debrief your participants after the study, informing them of any deception and allowing them to withdraw their data is they wish so after reflection.
- About Experiments
- What will you measure?
- This is called the dependent variable (DV)
- When you have decided what exactly what you would measure, you have operationalised the DV.
- You have to make sure that all the participants are actually doing the same work and would have specified what that task was (Such as a memory test).
- When you have decided what exactly what you would measure, you have operationalised the DV.
- This is called the dependent variable (DV)
- What are your 2 conditions?
- This is called the independent variable.
- There are often two conditions of the IV
- In this case it's either the TV is on or off.
- We need to compare both conditions(different levels of the IV)
- In this case it's either the TV is on or off.
- There are often two conditions of the IV
- This is called the independent variable.
- What will you expect to find?
- This is your hypothesis, a statement of what you believe to be true i.e STUDENTS WHO DO A MEMORY TASK WITH THE TV ON PRODUCE WORK WHICH GETS FEWER MARKS.
- This is different to the aims of an experiment, which would be to investigate the effect of TV on the work a student produces.
- Aims are intentions or possibly a research question.

- What will the participants do?
- You have worked out a standardised procedure
- It is important that each group does the same task in each condition
- Otherwise the results may vary because of changes in procedure, not changes in the IV.
- It is important that each group does the same task in each condition
- You have worked out a standardised procedure
- What do you need to control?
- You work out a set of standardized procedures
- You have tried to control some extraneous variables.
- Such as time of day
- You have tried to control some extraneous variables.
- You work out a set of standardized procedures
- What will you measure?
- RESEARCH AIM EXAMPLE: To investigate whether people do work just as well with the TV on, or will their work suffer as a result.
