Question

With the upcoming presidential election, Ira decided to create a survey to find out who might win. He carefully created a valid survey and gave it to five of his closest friends. He then tallied the results from the surveys and published his data in the school newspaper. Which of these would be a reason why Ira's results are not valid?

Answer 1

He only gave the survey to his closest friends, and not to a range of different people. This could create a bias.

Answer 2

After creating survey and collection of data, the interpretation is done. THe survey is usually done using a large number of people and not just five people. The result is not valid in the latter case.

Step-by-step explanation:

For conducting survey on the upcoming presidential election, Ira needs to get responses from a large number of people and not only five of his closest friends. If he collects from five of his closest friends, it could be biased or it could be based on shared opinion. But, if we consider a large group of people, the responses from a large audience would be varied and the results. would not be same as collected from five people.

For the survey data to be valid, Ira should collect information from a large audience and not five people.
