| Term | Definition |
| Qualitative data | 1. Information gathered in narrative (nonnumeric) form (e.g. a transcript of an unstructured interview). 2. Information gathered in numeric form. |
| Quasi-experiment | A type of experimental design where random assignment to groups is not employed for either ethical or practical reasons, but certain methods of control are employed and the independent variable is manipulated. |
| Questionnaire | A formal, written, set of closed-ended and open-ended questions that are asked of every respondent in the study. The questions may be self-administered, or interviewer-administered. A source of data. |
| Quine Tesis | An empirical test can never falsify an isolated hypothesis -- it actually challenges the whole knowledge system of which it is a part. |
| Quine-Duhem thesis | You cannot test a single hypothesis on its own, since each is part of linked set of theories. |
| Quota sample | Type of nonprobability sample which assigns interviewers quotas on preselected variables. |
| Quota sampling | 1. a non-probability sampling strategy where the researcher identifies the various strata of a population and ensures that all these strata are proportionately represented within the sample to increase its representativeness. 2. A sampling scheme similar to stratified sampling in which you first divide the population into classes (such as males and females) and then obtain a haphazard sample within each class. |
| 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). |
