Food Hygiene Rating Scheme (FHRS) Audit of Display and Business Survey 2022: Technical report
FHRS Audit Technical report 2022: Weighting
n line with standard market research practice, the data collected from the audit and telephone survey of food businesses was weighted to make it representative of the underlying population. Weighting the data was necessary because of the deliberate decision to stratify interviews to ensure sufficient base sizes were achieved by country and FHRS rating.
Weights were applied to the data to make it representative of the target population within each country. The weights were informed by the profile of the underlying population of businesses in terms of sector and FHRS. Data on the underlying population was sourced from FSA’s FHRS database and is presented in Tables 5.1-5.2.(footnote)
