Asurvey researcher chose to administer a survey using the internet. this sample likely over-represents people who own a computer and under-represents people who don't own a computer. this problem in the researcher's survey is best described as

selection bias

Explanation:

Selection bias is caused when a person is not able to select participants in a study randomly. The sample does not represent the population accurately.

Here, the survey is being conducted over the internet. The survey will obviously reach those members of the population which have computers. The people who do not have access to a computer will not be able to participate in the survey.
