Research Methods 6: Reliability
Cards in this deck (15)
- 1Define reliability.How consistent something is. If a certain measurement can be repeated and gain consistent results, the measurement is reliable.
- 2Define external reliability.Producing the same results each time the measurement is carried out.
- 3Define internal reliability. Give an example to support your explanation.A measure of how consistent something is within itself. For example, all the questions on a psychological test should measure the same thing.
- 4Define observer reliability.When two or more observers produce the same record of their observations.
- 5Describe the 'test - retest' method of assessing reliability.This is when a test/questionnaire/interview is administrated to the same participants on different occasions; if the same or very similar results are produced each time it is said to be reliable.
- 6What type of reliability does the 'test - retest' method assess?External reliability.
- 7Describe the 'split - half reliability' method of assessing reliability.This involves splitting the measuring device (test/questionnaire/interview) into two separate halves ad comparing a persons performance on both halves, if the performance is similar on both halves it is said to be reliable.
- 8What type of reliability does the 'split - half reliability' method assess?Internal reliability.
- 9Describe the 'Inter - Observer reliability' method of assessing reliability.This is where the observations of two or more observers, who observe the same event and make independent recordings, are compared for similarities. If they are similar, it is classed as reliable.
- 10What type of reliability does 'inter - observer reliability' assess?Observer reliability.
- 11How similar do results have to be before we can say they are reliable?They must correlate, to see how close the relationship between the two is. If the correlation is positive and significant, it is good.
'IF IT AIN'T +0.8, IT AIN'T GREAT' - 12How can we improve the reliability of questionnaires?Remove leading or ambiguous questions, or reword them so they are clearer.
Replace open - ended questions with close - ended questions, to avoid misinterpretation. - 13How can we improve the reliability of interviews?Use the same interview each time, which should be structured as these are more controlled.
Ensure all interviewers are properly trained. - 14How can we improve the reliability of experiments?Make sure all variables are operationalized and that procedures and instructions are fully standardised.
- 15How can we improve the reliability of observations?Ensure the behavioural categories are precisely defined and don't overlap.
Make sure all observers are properly trained.
