Random sampling occurs when each unit in the sample frame has a known positive probability of being included in the sample. Then units are selected randomly using a computer or random number table and the assigned probabilities. This type of sample is also called probability sampling.
A method of selecting households for verification in which the school district counts all of the applications on file as of October 31st of each school year, multiplies by 3%, and rounds upwards. Applications are randomly selected from those on file until the entire sample is selected.
the selection of a sample from a population so that each member of the population has an equal chance of being included. (43)
If subjects are drawn from a population such that each population member has equal probability of being selected.
a technique to select a sample which represents a population. People are chosen from the population at random, for example using randomly generated numbers.
the process of selecting subjects from a population such that each person in the population has an equal chance of being selected (Shavelson, 1996).
Selecting sample subjects such that each possible subject has a fixed and determinate probability of selection.
An excellent method of sampling in research, in which each member of the population has an equal chance of being included in the sample. [Go to source
Sample units that are selected in such a manner that all combinations of n units under consideration have an equal chance of being selected as the sample.
Drawing a number of individuals from a larger group or population, so that all individuals in the population have the same chance of being selected.
A sample drawn using a method whereby every member has an equal probability of being selected.
A method of probability sampling in which the probability of any individual being included in the sample is constant.
occurs when all the units in a population have an equal chance of appearing in the sample (180)
is a process by which people in a sample are chosen at random from a given population. For example, everyone in the population of 100 people can be assigned a unique number, then the numbers are put in a hat, and 40 numbers are drawn to choose 40 people to be in that sample. In a random sample, all of the people in the populations have an equal chance of being chosen.
the selection of a random sample; each element of the population has an equal chance of been selected
a strictly scientific sample
A procedure in which each member of the population has an equal chance of being included in the sample.
Process used in research to draw a sample of a population strictly by chance, yielding no discernible pattern beyond chance. Random sampling can be accomplished by first numbering the population, then selecting the sample according to a table of random numbers or using a random-number computer generator. The sample is said to be random because there is no regular or discernible pattern or order. Random sample selection is used under the assumption that sufficiently large samples assigned randomly will exhibit a distribution comparable to that of the population from which the sample is drawn.
Each and every element in a population has an equal opportunity of being selected.
The selection of individuals to participate in a public opinion poll (or other kind of study) in a way that is unbiased. See Public Opinion in the ThisNation online textbook.
Sampling in which every individual is selected at random.
A portion of the target population in which there is a high degree of probability that it contains at least some or all of the characteristics (educational level, background, intelligence quotients, etc.) of the infinite target population. The selection of the sampling is based on proven random sampling techniques (each sample selected is based on pure chance).
A selection process whereby each element in the population has an equal probability of being drawn.
A method of selecting participants for a study so that everyone in a population has an equal chance of being in the study.
The process of selecting units for a sample of size, so that all units have an equal chance of being selected as the sample. In auditing, it refers to how we obtain objective evidence.
Drawing a number of items of any sort from a larger group or population so that every individual item has a specified probability to be chosen.
A method by which subjects are selected to participate in a study in which all individuals in a population have and equal chance of being chosen. This helps to ensure the generalizability of the study results.
Every member of the population has an equal chance of being selected.
Random sampling is a sampling technique where we select a group of subjects (a sample) for study from a larger group (a population). Each individual is chosen entirely by chance and each member of the population has a known, but possibly non-equal, chance of being included in the sample. By using random sampling, the likelihood of bias is reduced. (From the Department of Statistics of the University of Glasgow, http://www.stats.gla.ac.uk/)
A method of selecting a sample whereby each element in the population has an equal chance (probability) of being selected for the sample.
A method of selecting units in such a way that all units under consideration have equal probabilities of being chosen.
A procedure for sampling from a population that gives each unit in the population a known probability of being selected into the sample.
is sampling method in which all elements in the population have an equal chance of being selected, and in which the value of one observation does not affect the outcome of other observations. [6
Selecting individual items from a large group in such a way that every individual item has the same chance of being included in the sample group.
A smaller group of people or objects chosen from a larger group or population by a process giving equal chance of selection to all possible people or objects. (H)
A sampling method in which all the units in a population have an equal chance of appearing in the sample. p. 183

Given a specified sampling procedure, all consumers within the universe have an equal chance for respondent selection.
