|---|---|---|---|---|---|
| biased sampling method | a sampling method that produces data that systematically differ from the sampled population.
🗑
|
||||
| cluster sample | a sample obtained by stratifying the population, or sampling frame, and then selecting some or all of the items from some, but not all, of the strata.
🗑
|
||||
| continuous variable | a quantitative variable that can assume an uncountable number of values.
🗑
|
||||
| data | the set of values collected from the variable from each of the elements that belong to the sample.
🗑
|
||||
| data value | the value of the variable associated with one element of a population or sample. This value may be a number, a word, or a symbol.
🗑
|
||||
| discrete variable | a quantitative variable that can assume a countable number of values.
🗑
|
||||
| experiment | a planned activity whose results yield a set of data.
🗑
|
||||
| finite population | a population whose membership can or could be physically listed.
🗑
|
||||
| infinite population | a population whose membership is unlimited.
🗑
|
||||
| judgment samples | samples that are selected on the basis of being judged “typical.”
🗑
|
||||
| multistage random sampling | a sample design in which the elements of the sampling frame are subdivided and the sample is chosen in more than one stage.
🗑
|
||||
| nominal variable | a qualitative variable that characterizes (or describes, or names) an element of a population.
🗑
|
||||
| ordinal variable | a qualitative variable that incorporates an ordered position, or ranking.
🗑
|
||||
| parameter | a numerical value summarizing all the data of an entire population.
🗑
|
||||
| population | a collection, or set, of individuals, objects, or events whose properties are to be analyzed.
🗑
|
||||
| probability samples | samples in which the elements to be selected are drawn on the basis of probability. Each element in a population has a certain probability of being selected as part of the sample.
🗑
|
||||
| proportional stratified sample | a sample obtained by stratifying the population, or sampling frame, and then selecting a number of items in proportion to the size of the strata from each strata by means of a simple random sampling technique.
🗑
|
||||
| qualitative variable | a variable that describes or categorizes an element of a population.
🗑
|
||||
| quantitative (or numerical) variable | a variable that quantifies an element of a population.
🗑
|
||||
| sample | a subset of a population.
🗑
|
||||
| sampling frame | a list, or set, of the elements belonging to the population from which the sample will be drawn.
🗑
|
||||
| simple random sample | a sample selected in such a way that every element in the population or sampling frame has an equal probability of being chosen. Equivalently, all samples of size n have an equal chance of being selected.
🗑
|
||||
| statistic | a numerical value summarizing the sample data.
🗑
|
||||
| statistics | the science of collecting, describing, and interpreting data.
🗑
|
||||
| systematic sample | a sample in which every kth item of the sampling frame is selected, starting from a first element, which is randomly selected from the first k elements.
🗑
|
||||
| variable | a characteristic of interest about each individual element of a population or sample.
🗑
