Reliability

About the lecture

In this lecture, we think about reliability, focusing in particular on: (i) test-retest reliability and its importance for ensuring that results reported by a study have potential to inform future work and practices; (ii) inter-rater reliability and its ability to combat researcher subjectivity and bias; (iii) internal reliability and the exemplar for this, which is the standardised exam.
