| Term | Definition |
| Rancangan Penelitian | Rancangan penelitian diartikan sebagai strategi mengatur latar penelitian agar penelitian memperoleh data yang valid sesuai dengan karakteristik variabel dan tujuan penelitian.’ PPKI (2000:15) |
| Random sampling | A process of selecting a sample whereby each member of the population has an equal chance of being included. |
| Random-digit dialing | Method of selecting telephone numbers for a sample, numbers are dialed randomly within working exchanges (i.e., the first three digits of a telephone number). |
| Randomisation | The random assignment of subjects to experimental and control groups (i.e. the allocation to groups is determined by chance). |
| Randomised controlled trial (RCT) | In a RCT, participants are randomly assigned either to an intervention group (e.g. a drug treatment) or to a control group (e.g. a placebo treatment). Both groups are followed up over a specified period of time and the effects of the intervention on specific outcomes (dependent variables) defined at the outset are analysed (e.g. serum cholesterol levels, death rates, remission rates). |
| Range | 1. A measure of variability indicating the difference between the highest and lowest values in a distribution of scores. 2. (requires ordinal measurement) a measure of dispersion; the lowest possible value (minimum) to the highest possible value (maximum) or a number representing the difference between the highest and lowest value for a set of observations. For example the weight range for a sample of adults could be 90 lbs. (minimum) to 300lbs (maximum)or expressed as the difference between 300 and 90 as a range of 210. |
| Rate | The number of occurrences of an event for a standard base, e.g. electrical rate (cost of .06898 for each kilowatt per day), water rate (cost per 1000 gallons of water used), crime rate (number of crimes per 100,000 population) |
| Ratio measure | A level of measurement that is characterized by being isomorphic with math as well as having a natural zero point. Ratio measures mathematically are isomorphic to arithmetic, meet all assumptions of arithmetic. Statistical functions appropriate include all functions of nominal, ordinal, interval measures as well as natural zero point based techniques. An example of a statistical technique for this level of measurement is the Geometric mean. Examples of ratio measures include weight, population density, age, income). |
| Ratio scale | Scores are assigned on a scale with equal intervals and also a true zero point (e.g. measurement in yards, feet and inches or in metres and centimetres). |
| Rational Choice Theory | All social phenomena as sum of individual choices (and nothing else). People make rational, optimal choices. |
| Rationalism | Truth can be best discovered through reason and rational thought. |
| 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. |

Hmm, it’s have been a while (a while???) since last time i wrote here. Skripsi is Indonesian terminology for a formal and lengthy research paper, especially a work of original research written in partial fulfillment of the requirements for a bachelor’s degree. I’m not sure about the equal English terminology for the Indonesian phrase strata satu, bachelor is the closest possible word that came into my mind. Whatever it is, with so many things in my mind, trying to share it with the entire world. :) |
