Question

A candidate to the presidency wants to know what percentage of the registered voters in the country would vote for him. So, he gives that task to one of his aides and tells him he has 3 days to come up with the results. Describe a method the aide should use to complete the task in time and which provides meaningful data. Use size of the sample, population of interest, and method of selection to complete your answer.

Answer 1

The population of interest are those above the voting age (ex. 18, depending on what country this is in). The size of the sample will depend on the population of the country, and the candidate will want to interview more people to get a representative sample if the country has a large population. Finally, for method of selection, a random and wide range of people must be surveyed. Ideally, we would want people from different professions, age groups, political parties, and geographical locations. Since the aide only has 3 days, the most practical decision may be to use online surveys spread around varying interest groups to get a wide range of data quickly.

Answer 2

Since the aide has only 3 days to come up with the results So, firstly he will collect the data of those people only who has the right to vote which is called the population of interest.

The size of the sample will depend on the population of the country.

Finally, for method of selection, a random and wide range of people must be surveyed. Ideally, he would want people from different professions, age groups, political parties, and geographical locations.

Since the aide has only 3 days, the most practical decision may be to use online surveys spread around varying interest groups to collect the information in the given short period of time. Because it is very difficult to collect this information in a very short period of time.
