Research methods psychology

What is an Independent variable (IV)?

• It is a variable

• This is the part of an experiment that is not changed.

• This is the part of an experiment that's changed or manipulated.

• The part of an experiment that is measured.

What is the Dependent Variable (DV)

• This is the part of an experiment that's changed.

• The results.

• Focus on a particular item for a selected period of time.

• The part of an experiment that is tested and measured.

What is Operationalizing variables

• A variable is operationalised when it has been been numbered.

• A variable is operationalised when it has been timed.

• A variable is operationalised when it has been identified.

• A variable is operationalised when it has been defined and turned in to something that can be measured.

What is validity?

• Validity refers to how accurately a method measures what it is intended to measure.

• Validity refers to how accurately a method can be described.

• Validity refers to how accurately the participants complete the test.

• Validity refers to how what is being measured.

What in internal validity?

• Internal validity refers to whether the effects observed in a study can be replicated after the study

• Internal validity refers to whether the effects observed in a study are due to the manipulation of the independent variable and not some other factor

• Internal validity refers to whether the effects observed in a study are due to manipulating the dependent variable.

• Internal validity refers to whether the effects observed will be replicated

What is external validity?

• External validity refers to the extent to which the conclusions from your research study can be generalized to the people outside of your study.

• External validity refers to the extent to which the conclusions from your research study can be used for research

• External validity refers to the extent to which the conclusions from your research study can be generalized in the lab

• External validity refers to the extent to which the conclusions from your research study are true

What is the aim of research?

• it summarises in a single sentence what you hope you will test

• it summarises in a single sentence what your sample will be

• it summarises in a single sentence what you learnt.

• it summarises in a single sentence what you hope to achieve at the end of a research

What are extraneous variables?

• Extraneous variables are all variables, which are not in order.

• Extraneous variables are all variables, which are not the independent variable, but could affect the results of the experiment.

• Extraneous variables are all variables, which are not the independent variable, as they were deleted from the study

• Extraneous variables are all variables, which are used in the study.

What is reliability?

• Reliability is consistency across researchers

• Reliability refers to the consistency of a research study, If findings from research are replicated consistently they are reliable.

• Reliability is consistency of the recruitment process

• Reliability refers to the sample repeating the same words

What is internal reliability?

• Internal reliability assesses the extent to which a measure varies from one use to another.

• Internal reliability assesses the consistency of the sampling method

• Internal reliability assesses the consistency the recruitment process

• Internal reliability assesses the consistency of results across items within a test
