Assume the Government wants to undertake a national study to understand how inflation is changing spending patterns among Australian adults. The findings from the survey would influence financial support packages to be made available, so it is very important to get results as accurate as possible. Remember, here in Australia voting is compulsory, so the Government has access to a good sample frame.
