C) Inter-rater reliability
D) Internal consistency
C
Feedback:
Investigator triangulation is conceptually analogous to inter-rater reliability in quantitative studies. Content validity is a term used in quantitative research that refers to the degree to which items in an instrument actually measure the intended concept. Construct validity in quantitative research refers to the validity of inferences gleaned from the study setting or an instrument used in the study in measuring the construct under investigation. Internal consistency in quantitative research refers to the degree to which sub-parts of a scale or instrument measure the same attribute or dimension.
