L0

Know the role

  1. Read a role through its responsibilitiesRequired

    Translate a role description into three observable learning goals.

L1

Build foundations

  1. Spreadsheet formulas and reconciliationRequired

    Build a sourced calculation table with an independent check.

  2. Statistics, samples and uncertaintyOptional

    Describe a distribution and its limits of inference.

  3. Analysis questions and metricsRequired

    Independently: Define the metric, denominator, period and dimensions of a business question.

  4. Data grain and cleaningRequired

    Independently: Define one row and identify missing, duplicate and unusual records.

L2

Develop core skills

  1. SQL filtering and aggregationRequired

    Independently: Practise SELECT, WHERE and GROUP BY and check results by hand.

  2. Joins and row multiplicationRequired

    Independently: Join customers and orders and reconcile row counts and totals.

  3. Charts and interpretationRequired

    Independently: Choose a comparison chart and write two observations.

L3

Practise scenarios

  1. Research, citation and argumentRequired

    Write a sourced analytical paragraph with limitations.

  2. Experiments and inferenceRequired

    Independently: Distinguish observational comparisons from randomised experiments.

  3. Recommendations and validationOptional

    Independently: Document metric definitions, findings, limitations and next steps.

L4

Build a work sample

  1. Present an inspectable work sampleRequired

    Submit a work sample with method, results and reflection.

Try a practice set

Calculations and choices receive immediate checks. Review open responses yourself against the rubric. All examples are educational.

1. 5 of 20 users convert. Conversion rate (%)?
2. How do you check user count after joining multiple orders?
3. After the experiments and inference task, state one assumption, one supporting fact and one condition that would change your conclusion.

Business metrics and data analysis report

For this business metrics and data analysis report, bound the problem to one educational scenario. List inputs and assumptions, preserve calculations and distinguish findings from missing evidence.

Define the question, scope and success criteria of this business metrics and data analysis report.

Record data, source links, dates, units and assumptions.

Write reproducible steps with calculations, evidence or a process map.

Separate observations, interpretation and recommendations.

List unknowns, validation steps and conditions that change the conclusion.
