Question	Answer
population	A _______ is the aggregate of all the elements that share some common set of characteristics, and that comprise the universe for the purpose of the marketing research problem.
census	A ______ involves a complete enumeration of the elements of a population.
sample	A ________, on the other hand, is a subgroup of the population selected for participation in the study.
parameter	A _______ is a summary description of a fixed characteristic or measure of the target population. A parameter denotes the true value which would be obtained if a census rather than a sample was undertaken.
statistic	A _______ is a summary description of a characteristic or measure of the sample. The sample statistic is used as an estimate of the population parameter.
target population	is the collection of elements or objects that possess the information sought by the researcher
element	is the object about which or from which the information is desired
sampling unit	is an element, or a unit containing the element, that is available for selection at some stage of the sampling process.
extent	refers to the geographical boundaries.
Defining the target population	involves translating the marketing research problem into a precise statement of who should or should not be included in the sample
Convenience sampling	attempts to obtain a sample of convenient elements. Often, respondents are selected because they happen to be in the right place at the right time
Judgmental sampling	is a form of convenience sampling in which the population elements are selected based on the judgment of the researcher.
quota sampling	a non probability which may be viewed as a two stage restricted judgemental sampling. ex. 50% male 50% female
sample frame	it's a list of potential participants
sample frame error	the list may not be updated (list is outdated)
snowball sampling	an initial group of respondents is selected, usually at random. 1 person starts to turn into more people
simple random sampling	each element in the population has a known and equal probability of selection.
systematic sampling	the sample is chosen by selecting a random starting point and then picking every ith element in succession from the sampling frame.
Stratified sampling	is a two-step process in which the population is partitioned into subpopulations, or strata.
cluster sampling	the target population is first divided into mutually exclusive and collectively exhaustive subpopulations, or clusters
cluster	each _________is heterogeneous in the inside but homogenous on the outside
strata	elements within a _______ is homogenous but heterogenous on the outside
geography	you build clusters around __________
returning to the field	The questionnaires with unsatisfactory responses may be ___________, where the interviewers recontact the respondents
Assigning Missing Values	If returning the questionnaires to the field is not feasible, the editor may ___________ to unsatisfactory responses.
discarding Unsatisfactory Respondents	In this approach, the respondents with unsatisfactory responses are simply discarded.
coding	means assigning a code, usually a number, to each possible response to each question.
data cleaning	if someone missed a question, dont just throw away the question. plug in a 99
codebook	contains coding instructions and the necessary information about variables in the data set
what are the non probability techniques	convinience, judgmental, quota, and snowball
what are the probability techniques	simple random, systematic, stratified ,and cluster
simple random	which sampling Difficult to construct sampling frame; expensive
snowball	which sampling is time consuming
statistical sampling	which sampling Can increase representativeness; easier to implement than SRS; sampling frame not needed
cluster sampling	which sampling is Easy to implement; cost effective
