What a finished DBA-831 Topic 4 sample selection critique looks like
The finished critique opens with the franchisor's reading: most respondents rated the new system favorably, so the network approves. It then asks how respondents came to be in the sample. The survey went to every franchisee, but responses came disproportionately from owners who adopted the system early, and franchisees who had filed complaints about it were less likely to reply. The critique states the likely direction of bias, toward approval, and uses the franchisor's own records to compare responders with nonresponders on adoption date, store volume and complaint history. Heckman's work on sample selection is cited for the general point that a self-selected sample can bias estimates when the reasons for responding relate to the outcome. The last section asks whether a franchisee can freely criticize a system the franchisor controls.
How a DBA-831 Topic 4 example is structured
Six parts move from the franchisor's conclusion to what the data can support. The first states the reading and the decision it is meant to justify, a mandate that every store adopt the system. The second describes how the sample formed, separating the complete sampling frame from the respondents, who selected themselves. A third part compares responders with nonresponders on characteristics already in company records, all figures illustrative. The fourth estimates the direction of bias and explains why the approval rate should be read as an upper bound. The fifth takes up ethics, drawing on the Belmont Report's principles of respect for persons, beneficence and justice, and asks whether answers from franchisees whose contracts the franchisor renews can count as freely given. The last part proposes a design the franchisor could run: an anonymous survey administered by a third party, with follow-up of a random subset of nonresponders.
Frame complete, respondents self-selected
Every franchisee received the survey, so the problem is not coverage but who chose to answer, and the critique keeps those two sources of error apart.
Responders compared with nonresponders
Adoption date, store volume and complaint history from company records show how the franchisees who answered differ from the ones who stayed silent.
Direction of bias stated plainly
Because early adopters answered more often and complainants less often, the favorable share is read as an upper bound on approval across the network.
Consent under contractual dependence
A franchisee whose renewal depends on the franchisor may not feel free to criticize its system, which weakens both the ethics and the evidence of the survey.
A redesign the franchisor could run
Third-party administration, guaranteed anonymity and follow-up of a random subset of nonresponders are proposed as a feasible way to test the approval claim properly.
Where marks go in DBA-831 Topic 4
The central weakness graders look for is a sample described as representative because everyone was invited. A complete frame with self-selected responses is still a self-selected sample, and papers that miss the distinction overstate what the approval rate shows. Stating that nonresponse may bias results, with no direction and no comparison, names a concern without estimating it. Critiques that recommend random sampling across the network ignore that the franchisor cannot compel an answer from anyone chosen. Ethics treated as a consent form misses the dependence built into the franchise relationship, which affects the data as much as the respondents. Papers that cite Heckman for a correction method they never apply, or attach findings to him beyond the selection problem, invite questions the paper cannot answer.

DBA-831 Topic 4 questions, answered
If everyone was surveyed, how can the sample be biased?
Because a sample is formed by who responds, not only by who is invited. When the reasons for answering are related to the question, such as satisfaction with the system being rated, respondents differ systematically from the whole population. A complete invitation list removes coverage error but leaves selection error untouched, and that is the problem the example traces in the franchisor's survey.
How can the direction of bias be estimated?
By comparing responders with nonresponders on characteristics already known for everyone, such as adoption date or complaint history, and asking how those characteristics relate to the outcome. Following up a random subset of nonresponders gives more direct evidence. The example uses both approaches with illustrative figures and treats the result as a bound on approval rather than a correction to it.
Does my study need ethics review if it is only a business survey?
Doctoral research involving people typically requires institutional review before data collection, whatever the setting, and research inside an organization raises particular concerns about consent and confidentiality when respondents depend on the sponsor. Follow the requirements your program and review board set. The example is DBA-831 coursework on a composite franchisor and does not substitute for that review.
