Welcome to your interview for the Research Scientist role at Concordia University.

The question is on your right: Validity and Reliability of Findings. Take a moment with it first.

Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen. You have three graded attempts to score 7/10 or better.

Only Submit answer is graded - discussion is free practice.

Problem

Scenario

You have completed a research study that includes a predictive model and supporting analysis. Your stakeholders want to know whether the findings are trustworthy, repeatable, and suitable for decision-making.

Question

How do you ensure the validity and reliability of your research findings?

What This Tests

  • How you validate findings beyond a single metric
  • How you use cross-validation to check stability
  • How you interpret calibration for probability outputs
  • How you use confusion-matrix thinking to connect results to decisions
