Identify the type of sampling bias guaranteed to occur in each of the sampling schemes, based on the information provided. Some sampling schemes may incur multiple types of bias.

sampling bias and response bias is most likely to occur.

Response Bias will likely occur here.

Step-by-step explanation:

for us to be able to understand the answers above we need to explain what sampling bias is and the Major types of sampling bias.

In statistics, sampling bias is a bias in which a sample is collected in such a way that some members of the intended population have a lower sampling probability than others.

A common cause of sampling bias lies in the design of the study or in the data collection procedure, both of which may favor or disfavor collecting data from certain classes or individuals or in certain conditions.

we have four major sampling bias which are;

1. Non response bias is the bias that results when respondents differ in meaningful ways from non respondents. Non-response is often problem with mail surveys, where the response rate can be very low.

2.Sampling bias: In the world of market research and surveys, sampling bias is an error related to the way the survey respondents are selected.

3.Response bias: is a general term for a wide range of tendencies for participants to respond inaccurately or falsely to questions.

4.Question order bias, or "order effects bias": is a type of response bias where a respondent may react differently to questions based on the order in which questions appear in a survey or interview. There are many ways that questionnaire items that appear earlier in a survey can affect responses to later questions.
