A 'funnel analysis' in product analytics shows:
Funnel analysis tracks user progression through a defined sequence (e.g., sign up → onboard → activate → pay) and measures conversion and drop-off at each stage.
2 / 14
DAU/MAU ratio measures:
DAU/MAU ratio measures stickiness — how frequently monthly users engage daily. A ratio of 0.5 means users engage on half their possible days — strong for most apps.
3 / 14
A 'cohort' in retention analysis is:
Cohorts group users by a shared attribute (often sign-up period) to track how their behaviour evolves over time — enabling comparison of how different cohorts retain.
4 / 14
Statistical significance in an A/B test means:
Statistical significance (typically p < 0.05) means the probability of seeing the observed difference by chance is low enough to conclude the difference is real.
5 / 14
The 'activation rate' metric measures:
Activation is the moment a user first experiences core product value (the aha moment). Activation rate measures what percentage of new users reach this milestone.

Sarah (Senior Product Analyst) comments on a code review for the new user onboarding flow. She asks you to add a metric tracking 'drop-off rate' at step 3. Which of the following best describes what Sarah is requesting?
A. A calculation to determine the average time users spend on each screen. B. A measurement of how many users begin the onboarding flow but don't complete it. C. An analysis of the number of new user accounts created per day. D. A report showing the percentage of users who upgrade to a premium subscription.
Sarah is requesting a metric related to *user behavior* and flow completion. The 'drop-off rate' specifically refers to the proportion of users who leave the onboarding process at a particular stage – this aligns with measuring how many start but don't finish. Options A and D are unrelated to the stated request, while option C focuses on new user acquisition, not completion rates.

David (Data Engineer) sends a Slack message: 'Just ran the daily cohort analysis. We're seeing a significant drop in retention for users acquired last month – almost 20% lower than the previous month.' What is David primarily highlighting?
A. The overall number of active users across all cohorts. B. A change in user behavior within specific groups (cohorts) over time, indicating potential issues with product engagement or onboarding. C. The performance of individual marketing campaigns driving new user acquisition. D. The total revenue generated by the application.
David's message focuses on *cohort analysis*, a common technique in product analytics. Cohorts group users based on shared characteristics (e.g., acquisition date), and tracking retention rates *between* cohorts reveals trends and potential problems with engagement over time. Option A is too broad; option C relates to marketing, not cohort analysis itself; and option D is unrelated to the message's content.

John, a junior developer, is writing a comment on a PR for the new product recommendation engine. He wants to ensure the team understands how they're measuring user engagement. Which of the following best explains what John should add to his comment?
John is focusing on measuring engagement. Tracking unique daily interactions aligns with a core product analytics goal – understanding how frequently and actively users are using the feature. The other options describe different metrics (session duration, return rate, API response) but don't directly address engagement in this context. It's important to clearly state what 'engagement' means when discussing data.

Maria, a product analyst, is reviewing the results of an A/B test for a new call-to-action button on the website. The experiment showed a 5% increase in click-through rate for variation B compared to variation A. Which statement BEST describes what Maria should conclude?
Maria needs to consider statistical significance. A 5% difference alone isn't enough; it must be determined if this change is likely due to chance or a real improvement. 'Statistically significant' means the results are unlikely to have occurred by random variation – crucial for making informed decisions about product changes. The other options either focus on baseline rates, premature deployment, or an arbitrary threshold.

During a standup meeting, the team discusses recent changes to the user segmentation model. Alex (Data Scientist) mentions that they've implemented a new metric: 'segment churn rate'. Which of the following best describes what Alex is referring to?
'Segment churn rate' specifically focuses on how different user groups are behaving. It measures the *rate* at which a particular segment is losing engagement – it's not just about overall product churn. This distinction is crucial because analyzing segment-level churn allows for more targeted improvements and personalized experiences. Option A describes overall churn, and options C & D are unrelated metrics.
11 / 14
You're reviewing a PR description for a new feature that calculates daily active users (DAU). The description includes the phrase 'tracking DAU trend over time'. What does this primarily indicate?
Tracking 'DAU trend' implies monitoring the *change* in daily active users over time. It's about identifying upward or downward trends and understanding why they're happening – potentially revealing issues with user acquisition, retention, or feature usage. Option A describes data resets, option C is a specific user segment focus, and option D relates to resource allocation.
12 / 14
Lisa (Product Manager) sends you this Slack message: 'Can we get some data on the drop-off rate for users completing onboarding step 4? It's been steadily increasing.' What is Lisa primarily asking for?
Lisa is specifically interested in the 'drop-off rate' – this refers to the percentage of users who *started* step 4 but didn't complete it. This highlights a potential problem area within the onboarding flow that needs investigation. Option A describes a broad overview, option B is a visualization, and option D focuses on time spent.
13 / 14
You're reviewing a code review comment from David (Senior Engineer) regarding the implementation of a new retention metric. He writes: 'We need to ensure we're calculating this cohort accurately – it must be based on the user's first activity date.' What is David emphasizing?
David is stressing the importance of defining a 'cohort' – a group of users who share a common characteristic (in this case, their first activity date). Using this initial date as the basis for tracking retention allows you to see how long users remain active *after* that starting point. Options A & D are related concepts but not the core emphasis here.
14 / 14
Maria (Product Analyst) is writing a PR description for a change to the user onboarding flow. She includes the phrase 'measuring activation rate post-flow'. What does this primarily mean?
'Activation rate' is specifically tied to whether new users are performing the *key actions* that indicate they're truly engaged with your product. Measuring this post-flow determines if the onboarding process effectively guides users towards these core behaviors. Options A & C focus on completion or subscription upgrades, while option D relates to feedback collection.
