Appendix 2: Technical Appendix

Method and sample

  • The data was collected by CATI interview (telephone survey).
  • The target group for this research study was recipients of Scotland’s Baby Box.
  • Sample was provided by the Scottish Government.
  • The final achieved sample size was 204.
  • The overall sample size of 204 from a known population of 11,469 provides a dataset with a margin of error of between ±1.35% and ±6.80%, calculated at the 95% confidence level (market research industry standard).
  • Fieldwork was undertaken between 6 th and 18 th October 2017.
  • Interviews lasted an average of 16 minutes.
  • All telephone interviews were recorded and a minimum of 10% were listened to in full for validation purposes. All interviewers working on the study were subject to validation of their work. In addition, interviewers were constantly monitored by the Telephone Unit Manager to ensure quality was maintained throughout each interview.
  • All research projects undertaken by Progressive comply fully with the requirements of ISO 20252.

Data processing and analysis

  • Our data processing department undertakes a number of quality checks on the data to ensure its validity and integrity.
  • For CATI questionnaires these checks include:
    • All responses logged by the interviewers are checked for completeness and sense. Any errors or omissions detected at this stage are referred back to the field department, who are required to re-contact respondents to check and if necessary, correct the data.
    • Data is entered into our analysis package SNAP and data is stored on CATI booths until imported and stored in our secure workfiles.
    • A computer edit of the data is carried out prior to analysis, involving both range and inter-field checks.
    • Where ‘other’ type questions are used, the responses to these are checked against the parent question for possible up-coding.
    • Responses to open-ended questions will normally be spell and sense checked. Where required these responses may be grouped using a code-frame which can be used in analysis.
    • Our analysis package is used and a programme set up with the aim of providing the client with useable and comprehensive data.
    • Cross breaks to be imposed on the data are discussed with the client in order to ensure that all information needs are being met.
