Sections can also participate in routing. | | **Question ID** | The stable identifier used to reference a question in logic, custom code, and analysis. | | **Display condition** | A rule that controls whether a question or section appears based on an earlier answer. | | **Jump logic** | A rule that directs a participant to another question or section after an answer. | | **Flow coverage** | A validation check that identifies questionnaire paths or items that cannot be reached. | | **Piping** | Inserting an earlier answer or variable into later question text or options. | | **Variable** | A reusable value defined for the questionnaire and referenced through piping or logic. | | **Stimulus** | An image, video, audio file, or other material shown for a participant to evaluate. | | **Custom code** | A React-based interface that replaces the built-in renderer for one question while keeping that question's answer contract. | | **Custom input** | An earlier answer declared for use by a custom-code question. | | **Custom text** | A translatable parameter exposed to custom code instead of hard-coded display wording. | ## Study lifecycle | Term | Meaning | | ----------------- | --------------------------------------------------------------------------------------------------------------------- | | **Draft** | The questionnaire and recruitment setup are being prepared. | | **Testing** | A participant test link is active. Saving questionnaire changes returns the study to Draft and invalidates that link. | | **Published** | The study is available to eligible participants and collects responses. | | **Completed** | Fieldwork has ended. | | **Test response** | A rehearsal submission created through the Test view; it does not count toward live results. | ## Recruiting | Term | Meaning | | ---------------------- | -------------------------------------------------------------------------------------------------------------------------------- | | **Panel** | One configured audience source with a response target, criteria, quotas, and provider links. | | **Panel provider** | The supplier that directs participants to the study. | | **Recruitment source** | Whether you supply the respondents for a panel or DeepField buys the fieldwork. | | **Feasibility** | How much of a requested sample can be collected in the fielding window, at the stated incidence and questionnaire length. | | **Screening question** | An opening question used to decide whether a participant can continue. | | **Screen-out** | The outcome when a participant does not meet a screening rule. | | **Incidence rate** | The estimated share of people in the source audience who qualify for the study. | | **Quota** | A target and optional cap for a participant group. | | **Quota cell** | One answer category or nested audience combination within a quota. | | **Natural fallout** | The sample distribution that results when a characteristic is not controlled by quota. | | **Direct invite** | A personal participation link created outside panel recruitment. | | **Credits** | The unit shown for an organization's available balance and coding charges. | | **Field** | One answer the researcher gets back. A question is one field however many options it offers; a matrix is one field per row. | | **Coding fees** | What a study costs to programme and analyse, charged in credits: a price for the study and a price for every completed response. | | **Recruiting fee** | What DeepField bills in euros for fieldwork it buys, quoted per panel before launch. | ## Responses and quality | Term | Meaning | | -------------------------- | ----------------------------------------------------------------------------------------------------- | | **Response** | One participant's survey session and submitted answers. | | **Answer** | The value stored for one question within a response. | | **Response status** | The recorded outcome, such as Completed, Screened out, Quota full, Abandoned, or Stopped for quality. | | **Rating** | A summary of the quality checks evaluated for a response. | | **Quality control preset** | The configured strictness used for automated quality decisions. | | **Excluded response** | A response manually removed from analysis; the exclusion can be reversed. | | **Transcript** | Timestamped text derived from an audio or video answer. | | **Raw answer** | The underlying stored value, including the structured value exported for a custom-code question. | ## Analysis | Term | Meaning | | ----------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **Base (n)** | The number of respondents represented by a figure or table column. | | **Filter** | A condition limiting the responses included in a chart or report view. | | **Breakdown** | A variable used to divide a measure into comparison groups. | | **Crosstab** | A table crossing row categories with one or more column groups. | | **Column group** | A question or variable whose categories form a set of crosstab columns. | | **Net** | A summary row combining several answer categories. | | **Significance letter** | A marker indicating that one crosstab column is statistically higher than the referenced column at the stated confidence level. | | **Theme** | A recurring pattern identified across open-text responses. | | **Persona** | A named respondent segment described in the generated analysis. | | **Saved chart** | A chart configuration stored in the study's chart library. | | **Analysis plan** | Saved questions, comparisons, filters, weighting, and output settings used to generate the plan folder. | | **Plan folder** | The protected chart folder a plan run builds in Charts, named after the plan. It holds each planned question's totals or theme charts and, where a comparison shows a significant difference on a testable base, its crosstab. Its charts are editable but cannot overwrite themselves: changes are kept with Duplicate & save, in one of your own folders. | | **Regeneration** | A new run of the saved plan that rewrites the plan folder. With the same output language, existing themes and analysis conversations are kept. | ## Weighting | Term | Meaning | | -------------------------- | ---------------------------------------------------------------------------------------------- | | **Weighting scheme** | A saved definition that adjusts how eligible responses contribute to analysis. | | **Target proportion** | The desired population share for a category. | | **Manual weight** | A multiplier assigned directly to a category. | | **Raking (rim weighting)** | An iterative method used to match targets across multiple weighting variables. | | **Weighted N** | The sum of response weights represented by a result. | | **Unweighted base** | The actual number of responses behind the weighted result. | | **Weighting efficiency** | A diagnostic showing how much effective information remains after unequal weights are applied. | ## Access and sharing | Term | Meaning | | -------------------- | --------------------------------------------------------------------------------- | | **Account type** | An organization-wide role: Admin, Researcher, or Collaborator. | | **Access level** | Permission on one study or folder: Owner, Editor, Commenter, or Viewer. | | **Inherited access** | Access received from a containing folder rather than granted directly on a study. | | **Guest link** | A no-sign-in link exposing selected study content for a configured period. | ## Check the result For a product action, follow the linked procedure and check its saved result rather than relying on a definition alone. ## Related * [Platform overview](/getting-started/platform-overview) * [Question types and custom code](/building-your-study/question-types) * [Troubleshooting and FAQ](/troubleshooting)
