Answer 1

Here, we are given that,

The Star Tribune Newspaper posted a survey online and asked people to click on the survey to indicate how they feel about the current mayor of Minneapolis.

Now, we have to answer the following question:-

Why does the author of our text think this is not the best way to gather good data on how the city feels about the mayor?

Answer :- Note that, while doing any survey, the basic requirement is that our sample or the units or people that we survey should be a good representative of the population.

That means, our sample should represent the Population well , showing all its characteristics.

The reasons why the author thinks that posting a survey online is not the best way to gather good data on how the city feels about the Mayor , are as follows:-

1. Many people in the city may not be browsing internet and coming online.

2. Even the people who come online, may or may not come across that survey.

3. Even among the people coming across it, some maynot express their opinions due to some reasons.

4. Some of old and illiterate people who may not have access to internet , may be not included in the survey as it is conducted online.

So, due to such reasons, the author thinks thinks that this is not the best way to gather good data on how the city feels about the Mayor.

The survey fails to fulfill the basic requirement of sampling and survey i.e. Unbiased and random sample which is a good representative of the population.

This answers your question.
