Document Summary

Idiographic explanations: involve a detailed story or description of the people that is based on empathetic understanding. Reliability: measures of social concepts must be reliable in that they produce the same results each time the same thing is measured. Replicability: a study must be able to be repeated and get the same results to fit this criteria, replication may sometimes be carried out to ensure the first study was carried out properly. Validity: concerned with the integrity of conclusions generated in research, 3 type of validity, measurement or construct validity: applied primarily to quantitative research; measures social concepts, refers to whether an indicator measures what it is intended to measure. If a measure of a concept is unstable/unreliable it automatically cannot be valid. Relationship with the general research orientation: 4 criterions of trustworthiness" help determine how good a qualitative study is, creditability: parallels measurement and internal validity, transferability: parallels external validity, dependability: parallels reliability, confirmability: parallels replicability.
