Decimals or fractions are accepted for numeric answers. Proofs and written responses use sample answers and require human marking. This is practice, not a protected examination.

1 Which term best matches this description: A statistical relationship that does not by itself establish causation.

Show answer and explanation

Association

Association is the matching concept in this lesson.

2 Which term best matches this description: A variable related to both an exposure and outcome that can distort interpretation.

Show answer and explanation

Confounder

Confounder is the matching concept in this lesson.

3 Which concept would you apply first in a situation where quantified or described limits on what the available data establish.

Show answer and explanation

Uncertainty

The scenario directly calls for Uncertainty.

4 Name the concept described as: The ability to repeat an analysis from documented data and methods.

Show answer and explanation

Reproducibility

The intended concept is Reproducibility.

5 Which statement about Association is most accurate?

Show answer and explanation

A statistical relationship that does not by itself establish causation.

The definition in the lesson notes gives the required condition.

6 Explain one important difference between Association and Confounder.

Sample answer and marking guidance

Association: A statistical relationship that does not by itself establish causation. Confounder: A variable related to both an exposure and outcome that can distort interpretation.

Credit a clear distinction using both definitions and an appropriate example if supplied.

7 Give a short example showing how Uncertainty would be used in practice.

Sample answer and marking guidance

A valid example should demonstrate this idea: Quantified or described limits on what the available data establish.

Credit a relevant scenario that applies the concept rather than merely naming it.

8 Summarize why Reproducibility matters in the lesson “Inference and responsible interpretation”.

Sample answer and marking guidance

Reproducibility matters because The ability to repeat an analysis from documented data and methods.

Credit the core purpose, scope and any important limitation from the notes.
