WORK6010 Chap.1 Evidence-Based HR and Research Questions
Evidence-Based HR and Research Questions
Evidence-based HR begins before a dataset is opened. A manager's concern must be converted into a bounded decision question with a defined population, outcome, time frame and possible action.
This chapter distinguishes business problems from research questions and hypotheses, then shows how scientific evidence, organisational data, professional expertise and stakeholder concerns can be combined without treating any single source as automatically decisive.
What this chapter covers
- 01
Frame an operational concern as a decision with a named audience and outcome
- 02
Separate a broad business problem from a researchable question and hypothesis
- 03
Combine scientific evidence, organisational facts, expertise and stakeholder values
- 04
Judge evidence by relevance, quality, context and transparency rather than prestige alone
- 05
Distinguish description, explanation, prediction and intervention questions
- 06
Record uncertainty and the evidence that would change a recommendation

Turn an attrition concern into a testable question
- +1The mark allocation in this exercise is not an official marking scheme. Define the population as analysts hired in the last 18 months and the decision as whether a bonus should be piloted.
- +1Define the outcome as voluntary departure within 12 months of hire, using a consistent departure classification.
- +1Ask whether eligible analysts offered the bonus have a different 12 month voluntary turnover rate from a credible comparison group.
- +1State the research hypothesis that bonus eligibility is associated with a lower voluntary turnover rate, alongside a null of no difference.
- +1Name a rival explanation such as manager quality, labour market demand or role assignment, and request evidence on it before a causal claim.
Key terms
- Evidence-based practice
- A disciplined decision process that combines several relevant evidence sources and makes the reasoning open to challenge.
- Business problem
- An organisational concern that requires a decision, such as unwanted turnover, weak performance or a safety risk.
- Research question
- A focused and answerable question that identifies what relationship, difference or change will be examined.
- Research hypothesis
- A precise expectation about the direction or form of a relationship that can be evaluated with evidence.
- Alternative explanation
- A plausible account of the observed pattern other than the explanation favoured by the initial claim.
Evidence-Based HR and Research Questions FAQ
What makes an HR question researchable?
It identifies a population, measurable outcome, time frame and comparison or predictor. It also connects to a real decision. 'Why are people unhappy?' is too broad; asking whether schedule control predicts a defined engagement measure among a named workforce over a stated period creates an analysable question.
Does evidence-based HR mean following research articles?
No. Published research is one evidence source. Organisational data, practitioner expertise, local constraints and stakeholder concerns also matter. The discipline is to assess each source's quality and relevance, explain how the sources fit together and make uncertainty visible rather than letting one authority end the discussion.
When is prediction different from explanation?
Prediction asks whether information improves forecasts for new cases. Explanation asks why a relationship exists. A model may predict departure using shift pattern and tenure without showing that changing either factor will reduce turnover. An intervention needs stronger design and a credible account of the mechanism.
How can I check whether a question is too broad?
Try to name the decision owner, population, outcome, time window and comparison in one sentence. If several cannot be named, narrow the question before selecting evidence. A strong question also permits an answer that could change the proposed action, rather than merely requesting data that confirm the manager's preferred story.
Exam move
Practise with short management claims taken from each weekly topic. Rewrite every claim as a four-part question: population, outcome, time and comparison. Then label it descriptive, associational, predictive or causal. For each question, list the evidence already available and one source that is missing.
Finish by writing a recommendation with a boundary, such as piloting an intervention while measuring uptake and voluntary departure. This routine prepares you for oral questioning because it makes your assumptions explicit. It also prevents method-first answers in the exam: a statistical technique should appear only after the decision, variables and design are clear. Add a short evidence matrix to each case.
Give one row to research evidence, one to local workforce data, one to practitioner knowledge and one to employees affected by the choice. Record what each source contributes and one reason it might mislead in this context. Next, reverse the preferred recommendation and ask which observation would make that alternative more credible. This adversarial step exposes assumptions that a neat hypothesis can hide.
When rehearsing aloud, state the management concern in ten seconds, the testable question in twenty and the bounded recommendation in thirty. Use the remaining time to defend the comparison and the strongest rival explanation. The sequence mirrors a useful oral answer because it demonstrates judgment before technical vocabulary.
