To determine

Whether the data collected in the online poll is good or bad.

Expert Solution & Answer

Answer to Problem CS

Solution: The data collected in the opinion poll is not good because the voluntary response sample is used to choose the samples.

Explanation of Solution

In the provided online poll, the respondents provide their choice against the question whether the marijuana should be legalized or not. Here, the poll allowed the individuals to select themselves as a respondent, since the poll does not force anyone to answer the question and the persons who wish to answer the question can provide the opinion through the website.

Hence, it can be said that the voluntary response sample is used for the study, which is a biased method of selecting the samples from the population for any study. The voluntary sample cannot represent the true population and the collected data may represent only a specific portion of the population.

Therefore, it can be said that the data collected in the online poll is not good.
