Reliability

• Reliability is when the measures are consistent over time when we repeat the experiment. It can also have confounding variables interfere with the variables and reduce the reliability.
• Validity is wether the results are accurate
• Standardised procedures are a set of events that is the same every time to minimise variation
• Inter-observer reliability is when different observers produce the same results when they witness the same sequence of behaviour
• Test reset method is when participants complete two different tests at different times and if their first and second results are correlated its reliable
• Split half method is participants take the test once then half the test (odd and even numbers) and get a correlation to show its consistent throughout.
• Observable actions are any kind of behaviour that can actually be seen or directly measured
• Mental processes and experiences are internal or hidden from view and cannot be directly observed
• Objectivity is to carry out an investigation without letting personal bias affect the results
• Subjectivity is letting personal bias corrupt experiment results
• Internal validity is when human behaviour correctly measures what its supposed too
• Concurrent validity is a way of assessing validity by comparing results from a new study to an established study that measures the same behaviour and see if there is any correlation
• Predictive validity is how well a test measures future behaviours
• Ecological validity is wether results from the lab are valuable as they are in an unrealistic environment with might alter behaviour so cannot or can be generalised
• Generalisability refers to wether results can be applied beyond research purposes
• Quantitive is mathematical data
• Qualitative is literacy data
• Primary data is first hand data gathered by researchers themselves
• Secondary data is the data from already existing sources
