Non-response Bias
Non-response bias is a specific form of sampling bias that occurs when individuals who choose not to participate in a survey differ systematically from those who do complete it. Even when a study employs careful random sampling, this bias can skew results and lead to inaccurate conclusions because the final respondents no longer accurately represent the original intended sample.

What type of systematic error occurs when the method used to select participants results in a sample that fails to accurately represent the broader target population?
A researcher wants to study stress levels among all undergraduate students at a university. She collects her data by distributing surveys exclusively to students who visit the campus counseling center. Because every person surveyed is a real undergraduate student at the university, this method produces a sample that accurately represents the broader undergraduate population.
A research team is designing several psychology studies. Match each intended target population with the sampling method that would most likely introduce sampling bias by systematically excluding important segments of that group.
A researcher intends to study the average stress levels of all employees at a large corporation but decides to recruit participants only from the company’s voluntary 'Stress Management and Yoga' workshop. Arrange the steps below to analyze the logical sequence of how this specific selection method results in a failure to accurately represent the broader population.
A researcher is developing a study to measure the average physical activity levels of all senior citizens (aged ) living in a large city. To create a sampling plan that effectively minimizes sampling bias and ensures the results can be generalized to the entire elderly population, which of the following procedures should the researcher implement?
A researcher claims that a new mindfulness intervention is effective for 'all university students' based on a study that only recruited participants from highly competitive 'Advanced Statistics' courses. When evaluating the validity of the researcher's generalization to the entire student body, a critic would argue that the conclusion is flawed because the selection method introduced _____.
A systematic error that occurs when the method used to select participants results in a sample that fails to accurately represent the broader target population is known as _____ bias.
A developmental psychologist wants to study the sharing behavior of all three-year-old children in a city. She collects her data by observing children who attend an expensive private daycare. If these children differ in important socioeconomic ways from the overall population of three-year-olds in the city, this selection method introduces sampling bias, meaning the findings cannot be safely generalized.
A researcher aims to study the average sleep quality of all university students but only surveys students leaving the campus library at midnight. Analyze this research scenario by matching each component of the study with its role in the context of sampling bias.
Evaluate the threat of sampling bias on a study's generalizability by ordering the steps a researcher must take to determine if their findings can be safely generalized.

Non-response Bias
Which of the following scenarios best illustrates an individual who would be classified as a survey non-responder in a psychological study?
In a study on adolescent sleep habits, a researcher selects a random sample of 300 teenagers. One teenager, who is part of the selected sample, receives the survey invitation but never completes it because they are preoccupied with a sports tournament. Even though the teenager did not explicitly refuse to participate, they are still classified as a survey non-responder.
Analyze the following scenarios involving a random sample of students in a social psychology study. Match each student's specific behavior or situation to the primary reason they are technically classified as a 'survey non-responder'.
A psychology researcher needs to assess how survey non-responders might have affected the validity of their research findings. Arrange the steps of this evaluative process in the correct logical sequence, from initial identification to the final appraisal of the results.
According to the definition of a survey non-responder, which of the following is a recognized reason why a selected individual might fail to complete a questionnaire?
In psychological research, an individual is classified as a survey non-responder only if they provide an explicit refusal to participate in the study.
An individual who is selected for a survey sample but fails to complete the questionnaire is known as a survey _____.

Which of the following best defines non-response bias in a research survey?
Non-response bias only affects studies that fail to use random sampling initially, as a carefully randomized starting sample guarantees accurate conclusions regardless of who actually completes the survey.
A research team uses random sampling to select participants for various studies but encounters high non-response rates. Match each scenario to the way non-response bias is most likely to systematically skew that study's conclusions.
A social psychologist is conducting a survey on 'community trust' in a large city. Sequence the following events to demonstrate the analytical process by which non-response bias leads to a failure in external validity.

Match each research concept with the description that best defines its role in survey methodology.
A researcher conducts a survey using a random sample but observes a low response rate of only . Which of the following conditions would prevent this low response rate from resulting in non-response bias?
A research team concludes that 'substance abuse is extremely rare' among college students after finding that only of survey respondents admitted to frequent drug use. If students who engage in heavy substance use were systematically less likely to return the survey due to privacy concerns, the team's final evaluation of the problem's severity is a(n) _____ of the true prevalence.
A researcher uses random-digit dialing to select a sample of 1,000 citizens for a survey on community safety. Since the researcher used careful random sampling to generate the initial list, the study's results will not suffer from non-response bias even if 60% of the selected citizens decline to answer the phone.
A research team analyzes the results of a mail-in survey on exercise habits and finds that individuals who regularly work out responded at a 90% rate, whereas sedentary individuals responded at a 10% rate. Because the individuals who chose not to participate differ systematically from those who did, the survey results are compromised by a specific type of sampling bias called _____.
A psychologist is evaluating a completed survey study's internal and external validity. Order the sequence of events showing how non-response bias systematically compromises the researcher's final conclusions, starting from the initial sampling stage.
