| Term | Definition |
| Reactivity | The ways in which the process of asking people questions affects their answers to other questions. |
| Realism | Things exist, whether or not people are thinking of them. |
| Recode | Classification of a variable's attributes into a smaller number of discrete categories for presentation or in order to test and observe the results of the new classification. An example is the classification of educational achievement into grade 1-12 as category (1) and more then 12 years as category (2). This would allow one to more easily examine data and see if a high school degree made a significant difference. Other examples of recoding include classification of crime rates into (1) High, (2) Medium, and (3) Low. |
| Recoding | The process of combining categories within a variable. |
| Referat | Referat adalah kertas kerja yang disampaikan dalam pertemuan ilmiah (seminar, konferensi). |
| Reliability | Reliability is concerned with the consistency and dependability of a measuring instrument, i.e. it is an indication of the degree to which it gives the same answers over time, across similar groups and irrespective of who administers it. A reliable measuring instrument will always give the same result on different occasions assuming that what is being measured has not changed during the intervening period. A number of techniques can be used to ensure the reliability of a standardised measuring instrument such as an attitude questionnaire, personality test or pressure sore risk calculator. These include test-retest, split-half and alternate forms. There are also statistical tests that can be used to assess reliability such as Cronbach Alpha and the Spearman rho correlation coefficient test. |
| Replication | Outcome of elaboration in which the control variable has no effect on the original relationship between the two variables. |
