In research, reliability relates to the consistency of a particular study or test. Assessment may involve whether the study has a generalisable sample and the setting in which it was carried out. On the other hand external validity refers to the extent to which the results can be generalised to other settings, people or time periods. It can be assessed by looking at wether adequate controls have been used / counterbalancing / controlling extraneous variables / standardisation etc. Validity refers to the extent to which a test measures what it sets out to measure. For example, a study may have strong internal validity if there is a causal relationship between the independent variable and dependent variable.
