Question

determine whether the sample may be biased. a company randomly selects 500 customers from its computer database and then surveys those customers to find out how they like their service.

Answer 1

Based on the information provided, the sample may be biased. The reason being, the company has selected customers from its computer database which means that only those customers who have interacted with the company and have their data available in the database will be surveyed. This means that the company is not taking into account the customers who may have had a bad experience and did not interact with the company again, or customers who do not use digital platforms to interact with the company. These customers may have different opinions about the company's service and their exclusion from the sample can result in a biased sample.

Answer 2

Explanation:

Based on the information given, it is not possible to determine whether the sample may be biased or not.

However, there is a possibility that the sample may be biased if the company's computer database does not accurately represent its entire customer base. For example, if the database contains only a specific type of customers, such as those who frequently make large purchases, then the sample may not be representative of the company's entire customer base. In this case, the survey results may not accurately reflect the opinions of all the company's customers.

It is also important to consider other factors such as how the survey was conducted and how the questions were framed, as these can also affect the validity of the survey results
