  15. 15. • 150 sensors per car • 1.000 data points per lap • 200 Gigabytes move from track and factory every race weekend • 50 Data Engineers per race
  16. 16. –Kenny O’Donnell “You will make the best decision you can make.”
  17. 17. Gut Feeling Data-driven DecisionIntuition Scientific
  18. 18. METRICS 📈
  19. 19. A good metric is… • comparable to another time period, group, competitor,… • understandable for the target audience. • a ratio or rate • targeted to the right audience (developers, marketers, business development,…) • a behaviour changer.
  20. 20. • Qualitative metrics are unstructured, anecdotal, revealing, hard to aggregate. • Quantitative metrics are numbers and stats, hard facts but less insights. Discover Proof
  21. 21.
  22. 22.
  23. 23. VANITY METRICS • Vanity Metrics makes you feel good but doesn’t change how you’ll act. • Vanity Metrics are bad!
  24. 24. • Hits • PageViews • Visits • Users • Followers/friends/likes • Logins Only for Ad Inventory Count People Cross it with People Why they stuck or left? Count actions! What are the actions and value?
  25. 25. “STATISTICS” 🎲
  26. 26. CORRELATION • Understand Correlation/Causality • What is the relationship between two variables? • Correlation does not imply causation.

  30. 30. CORRELATION • Use R, Excel, Numbers or online tools to calculate the linear relationship between two variables. • Interpret a Correlation Coefficient r • +- 1:A perfect linear relationship • +- 0.70 strong linear relationship • +- 0.50 moderate linear relationship • +- 0.30: weak linear relationship • +- 0: no linear relationship
  31. 31. STANDARD DEVIATION • Standard Deviation (SD) is a measure that is used to quantify the amount of variation or dispersion of a set of data values. • A standard deviation close to 0 indicates that the data points tend to be very close to the mean of the set, while a high standard deviation indicates that the data points are spread out over a wider range of values.
  32. 32. STATISTICAL SIGNIFICANCE • Statistical significance is fundamental to statistical hypothesis testing (determine whether a null hypothesis should be rejected or retained) • In any experiment or observation that involves drawing a sample from a population, there is always the possibility that an observed effect would have occurred due to sampling error alone.
  33. 33. A/BTESTING 🎲
  34. 34. Find Correlation Test Causality Optimize the causal factor Correlation lets you predict the future Causality lets you change the future
  35. 35. • A/B testing (also known as split testing) is a method of comparing two versions against each other to determine which one performs better. • Testing takes the guesswork out of optimization and enables data-backed decisions that shift business conversations from “we think” to “we know.”
  36. 36. Goal:
 Drive traffic to theVodafone website. Winner: +6%
  37. 37. Goal:
 Increase sales. Winner: +38%
  38. 38. Goal:

  41. 41. Goal:
 Increase unique opens/clicks of email Winner: +86%
  42. 42. Goal:
 Reduce Bounce Rate Winner!
  43. 43. • Define a Hypothesis and Goal. • Define the minimum sample size. • Wait until the minimum sample size have run through the test. • Calculate if the differences between versions are statistical significant.
  44. 44. WHICH METRIC
  45. 45. start with WHY? How great leaders inspire action:
  46. 46. follow with WHAT? HOW? Metrics Tools, Persons,…
  49. 49. BEHAVIOUR
  50. 50. CONVERSION
  52. 52. A B C dimension datasource Why? visit for more information and analysis tools acquisition behaviour conversion easy|A|B|C|D| Audience
  54. 54. Acquisition Activation Retention Referral Revenue Customer Intent Fulfilment of Customer Intent How to users find you? Do users have a great first experience? Do users come back? Do users tell others? How do you make money?

 matters Keep people coming back Gest customers faster than you lose them Make people invite friends How many they tell, how fast they tell them Spend revenue getting customers Customers are worth more than they cost to get THREE ENGINES AARRR
 Metric Retention Referral Revenue
  57. 57. Facebook on early days had only 150k users, little revenue and many superior competitors …but 75% of users visit one or more times per day. And within one month of launching on a new campus, could acquire 90% of the students.
  59. 59. • Cohort analysis is a subset of behavioural analytics that takes the data from a product and rather than looking at all users as one unit, it breaks them into related groups for analysis. • These related groups, or cohorts, usually share common characteristics or experiences within a defined timespan.
  60. 60. CohortTrend LongitudinalTrendOnboardingTrend Percentage of Monthly Active Users (MAU) each week for 12 weeks
  61. 61. DON’T FORGET
  62. 62. Weather, Day of the week, Calendar Day, etc influence the User Behaviour and so the Metrics.
  63. 63. THANKYOU! 😊
