Q1Domain Verified
In the context of advanced growth analytics, which of the following calculated fields would be most effective in segmenting users based on their engagement decay rate over a specific period, allowing for proactive retention efforts?
` D) `(SUM(CASE WHEN event_date >= DATE_TRUNC('month', CURRENT_DATE - INTERVAL '1 month') THEN 1 ELSE 0 END) - SUM(CASE WHEN event_date >= CURRENT_DATE THEN 1 ELSE 0 END)) / SUM(CASE WHEN event_date >= DATE_TRUNC('month', CURRENT_DATE - INTERVAL '1 month') THEN 1 ELSE 0 END)`
`AVG(DATEDIFF('day', first_seen_date, last_seen_date))`
`SUM(CASE WHEN event_date BETWEEN DATE_TRUNC('month', CURRENT_DATE - INTERVAL '1 month') AND CURRENT_DATE THEN 1 ELSE 0 EN
`COUNT_DISTINCT(CASE WHEN DATEDIFF('day', last_purchase_date, CURRENT_DATE) > 30 THEN user_id ELSE NULL END)`
Q2Domain Verified
When designing a calculated field to dynamically adjust a growth metric based on user seasonality (e.g., holiday spikes), which approach leverages parameters most effectively for granular control and future adaptability?
Using a series of nested `IF` statements based on predefined date ranges for each season.
Calculating the average deviation from the mean over the past year and applying it as a fixed adjustment.
Creating a parameter for "Seasonal Adjustment Factor" and incorporating it into a multiplier within the metric calculation.
Hardcoding seasonal adjustment factors directly into the calculation.
Q3Domain Verified
Consider a scenario where you need to identify "sticky" users in a growth analytics platform. Which calculated field would best capture the concept of a user returning repeatedly within a short timeframe, indicating strong engagement and habit formation?
`COUNT_DISTINCT(session_id)`
`COUNT(event_id) / COUNT_DISTINCT(session_id)`
` D) `AVG(DATEDIFF('day', event_date, LEAD(event_date) OVER (PARTITION BY user_id ORDER BY event_date)))`
`COUNT_DISTINCT(CASE WHEN DATEDIFF('day', MIN(event_date), MAX(event_date)) <= 7 THEN user_id ELSE NULL EN
