Mr. Tjersland is running for President. You are his campaign manager and you need to find out what percentage of the registered voters in the country will vote for him. There are a few things you could try.
Option I : Call all registered voters on the phone and ask them who they will vote for.
Although this would provide a very accurate result, it would be a very tedious and time consuming project. All registered voters represent the population of interest here, and a better approach would be to use a sample.
Option II : Call 4 registered voters, 1 in each time zone, and ask them who they will vote for.
Although this is a very easy task, the results would not be very reliable. To use a sample to make inferences about a population, the sample should be representative of the population. How likely is it that these 4 registered voters would represent the population of all registered voters? Not very! The sample needs to look just like the population, but smaller.
