So therefore you would start with a random number and use every fourth number in that sample.In my case I numbered the counties in the north and south of England, there were approx 23 in the south, so I did the following equation: 30(the sample size I needed) / 23(number of counties approx) = 1.2 (approx). This meant I chose 1 postcode from each of my registered counties and from every 5th county I took an extra postcode.From the north I did the same equation but I used 20(approx) counties, so the equation this time was: 30(sample size needed) / 20(number of counties approx) = 1.5. This meant I took 1 postcode from every county and an extra postcode from every second county.
