The phrase "ad hoc question" is correct and usable in written English.
It is typically used to refer to a question that is created for a specific purpose or situation, often in a spontaneous or impromptu manner.
Example: "During the meeting, I raised an ad hoc question about the project's timeline that sparked a valuable discussion."
Alternatives: "specific question" or "improvised question".
Data scientists need to be carefully equipped with proper tools and access to company-wide data so they can answer ad hoc questions, perform exploratory data mining, support BI teams, and help with data productization.
All ad hoc questions were pilot tested and showed acceptable variability and response rates.
Additionally, no validated instruments measuring the GPs' satisfaction with their own contribution to the patient's cancer rehabilitation course were available, and ad hoc questions were constructed.
A first explanation is that in some studies the measuring of the PCR was poor: some studies used validated questionnaires, while other studies used ad hoc questions.
As no pre-designed questionnaires for this specific purpose were available, ad hoc questions were constructed on the basis of previously used validated items [ 9, 16, 18].
As there were no validated instruments measuring patient satisfaction with their GP's contribution to their cancer course specifically, we constructed ad hoc questions.
14 months after inclusion, patient satisfaction with the GP regarding the cancer course and GP's satisfaction with own contribution to the patients' rehabilitation course were assessed using ad hoc questions specifically designed for this study.
Booklets for each time point were professionally printed and contained standardised questionnaires to evaluate various psychosocial outcomes and ad hoc questions to document sociodemographic characteristics, previous experiences of mammography, intention to return for further screening, and patient satisfaction.
This means that when addressing the "embedded" vs. "ad-hoc" question as in (2), the relevant economies of scale as in (1) have been reaped already.
