PROPORTIONATE/QUOTA SAMPLE FROM A UNIVERSITY Performing arts: 300 students Natural sciences: 300 students Humanities: 600 students Business & social sciences: 500 students Proportions: 3: 3: 6: 5  Minimum required is 3 + 3 + 6 + 5 = 17

PROPORTIONATE (QUOTA) SAMPLE Stage 1: Identify those characteristics which appear in the wider population which must also appear in the sample, i.e. divide the wider population into mutually exclusive homogeneous groups, one row for each characteristic. Stage 2: Identify the frequencies and proportions in which the selected characteristics appear in the wider population (as a percentage).

PROPORTIONATE (QUOTA) SAMPLE Stage 3: Ensure that the same percentages of characteristics appear in the sample. Stage 4: Calculate the totalled percentage and divide it by the highest common factor of the cells in that column. Stage 5: Add together the totals for the column to find out the total.
