||The data cube does allow customised tables to be produced with cells containing very small counts. To avoid any risk of disseminating identifiable data, a disclosure control technique called input perturbation has been applied to the data, with the exception of grand totals, whereby small random adjustments are made to cell counts. These adjustments (otherwise known as noise) allow for a greater amount of detailed data to be released and, as such, do not significantly impair the utility of the tabular data for use in broad level analysis. However, the relative impact of perturbation is larger for small cell counts, which therefore should be used with caution. Where unperturbed figures are required, users should consult the Higher Education Statistics published on the department’s website.
