What is a population?
The entire set of individuals or other entities to which study findings are to be generalized
What are probability sampling methods?
These are those in which the probability of selection is known and is not zero, so there is some chance of selecting each element
In a representative sample, some characteristics are overrepresented or underrepresented when compared to the population. true or false
false
What is my full first name
Victoria
What does taking a sample depend on?
Size of population and purpose of study.
What is a target population?
set of elements larger than or different from the population that was sampled, and to which the researcher would like to generalize any study findings.
What is simple random sampling
A sampling method in which every sample element is selected only based on chance through a random process
The demographic characteristics of people who use cell-phones only do not differ from the generational population. true or false
false
what season is my birthday in

What are the componets of a sample?
the population, sample, elements
Why do we want a diverse population?
Whatever y'all say it is most likely right haha!
what is stratified sampling
A sampling method in which sample elements are selected separately from population strata that are identified in advance by the researcher
A cluster is often some geographic unit. true of false
true
what is my coffee order
cold brew
What is Sample generalizability?
findings from a sample of the population can be generalized to the population from which the sample was selected
The individual members of the population whose characteristics are to be measured are called the elements. true or false
true
what is a nonprobabilty sampling methods
does not use a random selection procedure, meaning elements within the population do not have a known probability of being selected.
In a purposive sample, informants are selected (at least in part) because they have necessary characteristics for the study. true or false
true
what my favorite color
purple and yellow
What is a sampling error
The differences between the characteristics of a sample and the characteristics of the population from which it was selected
What is cross-population generalizability?
The findings from a study of one population can be generalized to another
What is quota sampling?
is intended to overcome the most obvious flaw of availability sampling—that the sample will consist of only whoever or whatever is available, without any concern for its similarity to the population of interest
Which two sampling methods require that the researcher know something about the salient characteristics of the population (such as race, ethnicity, or gender) before selecting samples?
a. Quota and multi-stage cluster
b. Simple random and stratified random
c. Multi-stage cluster and purposive
d. Stratified random and quota
Stratified random and quota
