experiments

• What is an independent variable?

  The variable a researcher manipulates.
• What is a dependent variable?

  The variable a researcher measures
• Define ‘operationalisation’

  When variables are clearly specified i.e. made precise
• Explain why operationalisation is important

  Increases objectivity (researchers do not need to subjectively interpret how to manipulate/ measure the variables) and

  replicability (they know how to manipulate/measure the variables in future research)
