What it covers

This programme covers the core statistical concepts every analyst needs: descriptive statistics, probability distributions, hypothesis testing, confidence intervals, and A/B test design. Participants work through realistic business datasets to move from data summaries to defensible conclusions. The format combines short concept modules with hands-on lab exercises using Excel, Python, or R depending on team preference. By the end, participants can independently design and interpret experiments and communicate uncertainty to non-technical stakeholders.

What you'll be able to do

  • Select the appropriate descriptive statistic for a given business question and explain why
  • Design a valid A/B test including sample size calculation, randomisation, and stopping criteria
  • Correctly interpret a p-value and confidence interval without overstating certainty
  • Identify at least three common statistical pitfalls (p-hacking, Simpson's paradox, survivorship bias) in a real dataset
  • Present statistical findings — including uncertainty — in a format accessible to non-technical decision-makers

Topics covered

  • Descriptive statistics: mean, median, variance, skewness, and when each matters
  • Probability distributions: normal, binomial, Poisson — recognising them in business data
  • Hypothesis testing: null vs. alternative, p-values, Type I and Type II errors
  • Confidence intervals and margin of error in plain language
  • A/B test design: sample size, power, and stopping rules
  • Correlation vs. causation and Simpson's paradox
  • Common statistical pitfalls: p-hacking, survivorship bias, base rate neglect
  • Communicating statistical findings to non-technical audiences

Delivery

Typically delivered as a 2–3 day in-person or live-virtual programme split across multiple sessions to allow reflection between modules. Approximately 40% concept delivery and 60% hands-on lab work using real or realistic business datasets. Materials include annotated slide decks, lab notebooks (Excel or Jupyter), a cheat-sheet reference card, and a take-home case study. Remote delivery works well with breakout rooms for group exercises; in-person preferred for cohort bonding and live dataset exploration.

What makes it work

  • Anchoring every statistical concept to a real business decision the team already faces
  • Requiring participants to bring one live dataset from their own work to the lab sessions
  • Establishing a shared review checklist for experiment design that the team uses after the training
  • Following up 4–6 weeks post-training with a short office-hours session to review live experiments

Common mistakes

  • Running A/B tests without pre-calculating required sample size, leading to underpowered or over-run experiments
  • Treating p < 0.05 as proof of business impact rather than as a signal to investigate further
  • Confusing correlation with causation when presenting dashboard insights to leadership
  • Stopping tests early when results look promising, inflating false-positive rates

When NOT to take this

This training is not the right fit for a team that already runs hundreds of experiments per month with a dedicated data science function — they need advanced causal inference or Bayesian methods training, not statistical foundations.
