What does reliability measure in a study?
It measures the consistency of a study and its results.
How does the reliability have issues?
Issues can arise from the procedures, measuring tool results, and the researcher.
What is a procedure issue in reliability?
It questions whether participants have been given the same instructions, task, and experimenter.
Standardized procedures can help ensure consistency.
What is a measuring tool issue in reliability?
It occurs when the same measuring tool yields different results.
Example: An IQ test taken twice with differing scores indicates unreliability.
How can measuring tool issues be resolved?
By using a reliable and accurate measuring tool.
What is a researcher issue in reliability?
It refers to inconsistencies in how researchers record data and observations.
Example: Two researchers observing the same behavior may report different results.
How can you fix researcher reliability issues ?
Check the categories measurements are not too complicated
that the researchers are observing using the same code sheet
How can you fix procedure reliability problems?
Standardised procedure - everyone gets the same conditions
What is a test-retest check?
It is a method to assess reliability by having a participant take the same test multiple times.
What does a test-retest check reveal?
It reveals if a measuring tool consistently yields the same results over time.
What is inter- rater reliability?
When more than one observer observe using the same code sheet
What is the inter - Rater reliability of reliability comes out as showing poor reliability?
Change the behavioural current categories as they may be too similar
Observers may need more training
What if a test retest comes out as showing poor reliability?
The questionnaire might need changing
How can you improve the reliability of an experiment?
Same environment, the researcher standardised instructions
How can you improve the reliability of correlation?
Check measuring tools
The co variables for reliability
How can you improve the reliability of observations?
You structured and controlled observation
Film behaviour
Have more than one observer and conduct an inter rater reliability check
Categories should be measured and clear e.g operationalised
How can he improve the reliability of a questionnaire?
Only closed questions
remove anything that is unreliable and assess with pilot study
How you can improve reliability of an interview ?
Have the same interviewer interview each participant
Structured interview
