== Week 4 - Introduction ==
'''[[w:Market research|Market research]]''' is any organized effort to gather information about [[w:target markets|target markets]] or customers.  It is a very important component of [[w:business strategy|business strategy]]. The term is commonly interchanged with [[w:marketing research|marketing research]]; however, expert practitioners may wish to draw a distinction, in that ''marketing'' research is concerned specifically about marketing processes, while ''market'' research is concerned specifically with markets. ( Wikipedia )

'''[[w:Marketing research|Marketing research]]''' [...] is the systematic gathering, recording, and analysis of [[w:qualitative|qualitative]] and [[w:quantitative|quantitative]] data about issues relating to marketing products and services. ( Wikipedia )

== Week 5 ==
In [[w:sociology|sociology]], '''[[w:quantitative research|quantitative research]]''' refers to the systematic empirical investigation of social phenomena via statistical, mathematical or numerical data or computational techniques. ( Wikipedia )

'''[[w:Qualitative research|Qualitative research]]''' is a method of inquiry employed in many different academic disciplines, traditionally in the [[w:social sciences|social sciences]], but also in [[w:market research|market research]] and further contexts. Qualitative researchers aim to gather an in-depth understanding of [[w:human behavior|human behavior]] and the reasons that govern such behavior. The qualitative method investigates the ''why'' and ''how'' of [[w:decision making|decision making]], not just ''what'', ''where'', ''when''. Hence, smaller but focused [[w:Sample (statistics)|sample]]s are more often used than large samples. ( Wikipedia )

== Week 6 ==
A field of applied [[w:statistics|statistics]], '''[[w:survey methodology|survey methodology]]''' studies the [[w:sample (statistics)|sampling]] of individual units from a [[w:population (statistics)|population]] and the associated [[w:survey data collection|survey data collection]] techniques, such as [[w:questionnaire construction|questionnaire construction]] and methods for improving the number and accuracy of responses to surveys. ( Wikipedia )

== Week 7 ==
A '''survey''' involves interviews with a large number of respondents using a predesigned questionnaire ( Teacher )

A '''[[w:questionnaire|questionnaire]]''' is a [[w:research|research]] instrument consisting of a series of [[w:question|question]]s and other prompts for the purpose of gathering information from respondents. Although they are often designed for [[w:statistics|statistical]] analysis of the responses, this is not always the case. ( Wikipedia )

'''[[w:Questionnaire construction|Questionnaire construction]]''' regards questionnaires. It is a series of questions asked to individuals to obtain statistically useful information about a given topic. ( Wikipedia )

'''[[w:Quantitative marketing research|Quantitative marketing research]]''' is the application of quantitative research techniques to the field of marketing. It has roots in both the positivist view of the world, and the modern marketing viewpoint that marketing is an interactive process in which both the buyer and seller reach a satisfying agreement on the "four Ps" of marketing: Product, Price, Place (location) and Promotion.

In [[w:statistics|statistics]], [[w:quality assurance|quality assurance]],  & [[w:Statistical survey|survey methodology]], '''[[w:Sampling (statistics)|sampling]]''' is concerned with the selection of a subset of individuals from within a [[w:population (statistics)|statistical population]] to estimate characteristics of the whole population. ( Wikipedia )

A '''[[w:Data sample|Data sample]]''' is a set of [[w:data|data]] collected and/or selected from a [[w:statistical population|statistical population]] by a defined procedure. ( Wikipedia )

* '''[[w:Sampling (statistics)|Sampling]]''' is the use of a subset of the [[w:population (statistics)|population]] to represent the whole population. ( Wikipedia on [[w:Nonprobability sampling]] )  
:::'''Probability sampling''', or '''[[w:random sampling|random sampling]]''', is a sampling technique in which  the [[w:probability|probability]] of getting any particular sample may be calculated.  
:::'''Nonprobability sampling''' does not meet this criterion and should be used with caution. Nonprobability sampling techniques ''cannot'' be used to infer from the sample to the general population. ( Wikipedia )

* '''[[w:Systematic sampling|Systematic sampling]]''' is a [[w:statistics|statistical method]] involving the selection of elements from an ordered [[w:sampling frame]]. ( Wikipedia )

* '''[[w:Stratified sampling|Stratified sampling]]''': In [[w:statistical survey|statistical survey]]s, when subpopulations within an overall population vary, it is advantageous to sample each subpopulation (stratum) independently. '''Stratification''' is the process of dividing members of the population into homogeneous subgroups before sampling. ( Wikipedia )

* A '''[[w:simple random sample|simple random sample]]''' is a subset of [[w:individuals|individuals]] (a [[w:sample (statistics)|sample]]) chosen from a larger set (a [[w:statistical population|population]]). 
:::Each individual is chosen [[w:randomization|randomly]] and entirely by chance, such that each individual has the same [[w:probability|probability]] of being chosen at any stage during the sampling process, and each subset of ''k'' individuals has the same probability of being chosen for the sample as any other subset of ''k'' individuals. This process and technique is known as '''simple random sampling''', and should not be confused with [[w:Systematic sampling|systematic random sampling]]. A simple random sample is an unbiased surveying technique. ( Wikipedia )

== Week 16 ==

* '''[[w:Primary research|Primary research]]''' consists of a collection of original primary data collected by the researcher.  It is often undertaken after the researcher has gained some insight into the issue by reviewing secondary research or by analyzing previously collected primary data. ( Wikipedia )

* '''[[w:Secondary research|Secondary research]]''' (also known as desk research) involves the summary, collation and/or synthesis of existing research rather than [[w:primary research|primary research]], where data is collected from, for example, research subjects or experiments. ( Wikipedia )

* A '''[[w:Back-translation#Back-translation|Back-translation]]''' is a translation of a translated text back into the language of the original text, made without reference to the original text. ( Wikipedia )

* The '''[[w:European Society for Opinion and Market Research|European Society for Opinion and Market Research]]''' ('''[[w:ESOMAR|ESOMAR]]''') is a world association for market, social and opinion researchers.

( Wikipedia ) An example are the ''' closing values over [[w:time|time]] of [[w:stock market index|stock market index]] ( jubo-jubo )

In [[w:data processing|data processing]], a '''[[w:pivot table|pivot table]]''' is a data summarization tool found in data visualization programs such as [[w:spreadsheet|spreadsheet]]s or [[w:business intelligence|business intelligence]] software. Among other functions, a pivot-table  can automatically sort, count total or give the average of the data stored in one table or spreadsheet.  It displays the results in a second table (called a "pivot table") showing the summarized data. ( Wikipedia )

A '''[[w:Likert scale|Likert scale]]''' is a [[w:psychometrics|psychometric]] scale commonly involved in research that employs [[w:questionnaire|questionnaire]]s.  It is the most widely used approach to scaling responses in survey research, such that the term is often used interchangeably with ''[[w:rating scale|rating scale]]'', or more accurately the '''Likert-type scale''', even though the two are not synonymous.  The scale is named after its inventor, [[w:psychologist|psychologist]] [[w:Rensis Likert|Rensis Likert]]. ( Wikipedia )
