Question

When a research company pulls a random sample of people from a phone book and that sample does not include people with unlisted numbers or who do not have landline telephone service, we say that the sample contains _____.

Answer 1

Answer:

sample selection error

Explanation:

According to my research on different types of sample methods, I can say that based on the information provided within the question this is an example that the sample contains a sample selection error. This refers to an error occurred when the sample deviates from the true characteristics, attributes and behavior of the total population. Since there are many unlisted numbers and people listed who do not have landlines the sample is flawed.
