Full purpose: To provide an understanding of the study design addressing a business case (e.g., research question); to provide information which would allow, for example, (a) a researcher to field or repeat a study, or (b) a statistician to recreate a statistic or finding, or (c) a data user to understand the methods used to collect the data..
Full description: A series of design specifications (see topic areas below), not necessarily in a predefined order, that as a whole, constitute the methodology. Also known as the study design. Such design specifications probably include the information in the proposed view Protocol Specification by Jay (Re: Protocol Specification)
Discussion (Steve, Dan, Simon, Barry, Nicole)
Topics in Scope
|Study Design||The "how"; specifications for how the research will be carried out and how the data will be obtained, collected, or captured.|
|Business Case||The "why"; statement of why the research will be conducted and the research question(s) that will be addressed.|
|Sample Frame||Identification of population upon which the survey will be conducted.|
|Sampling||Specifying how the sample will be drawn from the frame.|
See source link on sampling.
|Estimation||Consideration of costs, size, bias, and confidence in the design of the variance estimates.|
|Weighting||Representative power of each case in a data set and how they will be determined.||See source link on weighting.|
Editing/cleaning or coding during or in context of data collection or administration of instrument (contingent upon mode).
Examples include looking for out-of-bound values, data inconsistencies, reporting errors, recoded variables (variables created from existing values from other variables), or coding open-ended text into categories.
|Application or not to apply coding or a statistical technique to a dataset to populate missing values.|
Questionnaire development (logical instrument), mode effects
Creation of question types, response categories and options, skip logic, testing, mode of administration
Design of the data collection instruments and design of methodological tests (focus groups, cognitive interviews) to assist with instrument development. See source link on questionnaire design.
|Specification for how the units will be subdivided in samples, tables or analyses.|
Selection of strata, construction of data tables
Identification of analytic approach and specific statistical tests and manipulations.
- We need to decide those views that are critical to describing methodology but that are out of scope, such as Logical Instrument, Classifications, etc.
