Abel's sample is a proportionate stratified sample because he has divided the population (workers in different departments) into strata based on a relevant characteristic (absenteeism rate) and has selected a proportionate sample (10% from each stratum) from each group. This method allows for a more accurate representation of the overall population, and also allows for comparisons between the different departments.
