1
Q

Validity

A

Whether an observed effect is genuine and represents what is actually out there in the real world.

ie Is the result legitimate?

2
Q

Data Reliability

A

Data can be reliable but not valid

3
Q

Ecological Validity

A

Whether the findings can be generalised from one setting to another.
This is usually generalised to everyday life.

This may not be related to the setting (eg a lab) but more to the task that participants are asked to perform

4
Q

Temporal Validity

A

Findings should be consistent over time.

ie Do the findings remain true over time?

5
Q

Face Validity

How is this achieved?

A

Whether a test looks like it measures what it’s supposed to measure.

This is achieved by simply “eyeballing” the measuring instrument or by passing it to an expert to check

6
Q

Concurrent Validity

A

Whether the findings of one study are similar to those on a well-established test

7
Q

Correlation and Validity

A

Correlation coefficient should exceed +.80 for validity

8
Q

Improving the Validity of Experiments

A

Control groups and standardisation.

A control group means that the researcher is more confident that changes in the DV were due to the effect of the IV.

Standardised procedures minimise the impact of participant reactivity and investigator effects

9
Q

Improving the Validity of Questionnaires

A

Lie scale and confidentiality.

Lie scales control for the effects of social desirability bias.

Respondents are assured that all data submitted is confidential

10
Q

Improving the Validity of Observations

A

Good categories.

Behavioural categories that are well-defined, thoroughly operationalised and not ambiguous or overlapping

11
Q

Improving the Validity of Qualitative Research

A

Interpretive validity and triangulation.

Interpretive validity demonstrated through the coherence of the reporting and the inclusion of direct quotes from participants.

Triangulation involves using a number of different sources as evidence (eg interview data, personal diaries etc)

12
Q

Two ways of Assessing Validity

A

Face validity

Concurrent validity
