Operationalised, variables, characteristics, effects, randomisation etc.

Define the Operationalisation of variables

Ensuring that the variable you are studying is clearly defined and in a form that can be easily measured

The key strength of the experimental method is that….

The IV is manipulated, EV are controlled so the cause/effect can be measured on the DV

Define Demand Characteristics

Any cue from the researcher or from the research situation that may be interpretated by the participants as revealing the purpose of the investigation

What might demand characteristics lead to

P’s might deliberately or intentionally please or displease the researcher

What is Investigator effect?

Any effect of the investigator’s behaviour on the outcome of the experiment

What is Randomisation?

The use of chance in order to control for the effects of bias

Give one example of randomisation we can do in an experiment

pick names out of hats (explain in detail)

What is Standardisation

Using the same formalised procedures and instructions for all p’s in a research study

What is a control group?

The control group is the group of p’s who receive no treatment

What is the purpose of having a control group

Purpose is for comparison
