| show | Sampling Frame
🗑
|
||||
| Define Sample Components & the Population - Units that contain one or more elements and that are listed in a sampling frame | show 🗑
|
||||
| Define Sample Components & the Population - Units listed at each stage of a multistage sampling design; you sample both | show 🗑
|
||||
| Define Sample Components & the Population - Primary Sampling Units | show 🗑
|
||||
| show | Teachers; they are not the elements in the study
🗑
|
||||
| Evaluate Generalizability - Sample Generalizability | show 🗑
|
||||
| show | Can the findings from a study of one population be generalized to another, somewhat different population
🗑
|
||||
| Evaluate Generalizability - Sampling Error | show 🗑
|
||||
| show | From what population were the cases selected? What method was used to select cases from this population? Do the cases that were studied represent, in the aggregate, the population from which they were selected?
🗑
|
||||
| show | A set of elements larger than or different from the population sampled and to which the researcher would like to generalize study findings.
🗑
|
||||
| show | Identical
🗑
|
||||
| Assess the Diversity of the Population - Representative Sample | show 🗑
|
||||
| Consider the Census - Census | show 🗑
|
||||
| Give examples of census | show 🗑
|
||||
| show | Too expensive, Time Consuming, Its hard to get people to complete a survey,
🗑
|
||||
| show | Allow us to know in advance how likely it is that any element of a population will be selected; Relies on random, or chance, selection method so that the probability of selection of population elements are known.
🗑
|
||||
| Sampling Methods - Nonprobability Sampling Method | show 🗑
|
||||
| Sampling Methods - Probability of Selection | show 🗑
|
||||
| show | In which cases are selected only on the basis of chance, with a haphazard method of sampling; no control over the sampling method
🗑
|
||||
| show | Selecting elements from an incomplete list of the total population & failing to obtain an adequate response rate
🗑
|
||||
| show | Are likely to differ systematically from those who take the time to participate.
🗑
|
||||
| Explain the Probability Sampling Methods. | show 🗑
|
||||
| show | Over-representation/under representation of some population characteristics in a sample due to the method used to select the sample; A sample shaped by systematic sampling error is a biased sample
🗑
|
||||
| show | Systematic Bias
🗑
|
||||
| show | Systematic
🗑
|
||||
| show | Confidence
🗑
|
||||
| show | Homogenous
🗑
|
||||
| show | A method of sampling in which every sample element is selected only on the basis of chance, through a random process.
🗑
|
||||
| show | A table containing lists of numbers that are ordered solely on the basis of chance; It is used for drawing a random sample
🗑
|
||||
| show | Random Digital Dialing
🗑
|
||||
| Simple Random Sampling - Random Digit Dialing | show 🗑
|
||||
| Simple Random Sampling - Replacement Sampling | show 🗑
|
||||
| In many studies, we sample directly from the elements in the ______________ of interest | show 🗑
|
||||
| Which sampling method is more desirable to generalize a larger population? Probability or Nonprobability? | show 🗑
|
||||
| show | Larger
🗑
|
||||
| show | Homogenous
🗑
|
||||
| The _______ of the total population that a sample contains does not affect the sample's representativeness unless that fraction is _____. | show 🗑
|
||||
| show | Small Cards
🗑
|
||||
| Random Digit Dialing is particularly useful when a __________ _______ is not available. | show 🗑
|
||||
| show | No longer service, Businesses
🗑
|
||||
| Simply random sampling can be done either with or without ___________ ________ | show 🗑
|
||||
| show | Sampling in which elements are selected on the basis of convenience; available or easy to find
🗑
|
||||
| What is Availability Sampling also known as? | show 🗑
|
||||
| show | When a field researcher is exploring a new setting and trying to get some sense of the prevailing attitudes or when a survey researcher conducts a preliminary test of a new set of questions.
🗑
|
||||
| show | To overcome the most obvious flaw of availability sampling - that the sample will just consist of whoever or whatever is available, without any concern for its similarity to the population of interest
🗑
|
||||
| show | Quota Sampling
🗑
|
||||
| Purposive Sampling | show 🗑
|
||||
| show | Undermined
🗑
|
||||
| ____________ research often focuses on populations that are hard to locate or very limited in size. | show 🗑
|
||||
| What is one solution to remove random sampling from sampling error? | show 🗑
|
||||
| show | A mathematical tool for estimating how likely it is that a statistical result based on data from a random sample is representative of the population from which the sample is assumed to have been selected.
🗑
|
||||
| show | Differences between the population and the sample that are due only to chance factors (random error), not to systematic sampling error; Random sampling error may or may not result in an unrepresentative sample
🗑
|
||||
| show | Random Sampling Error (Chance Sampling Error)
