Session Data Analysis.

To analyze session data, you can use SQL queries to derive insights. For example:

1. Average Session Duration Above a Threshold: Calculate the average session duration for sessions exceeding a specific time (e.g., 180 seconds) using SELECT AVG(session_duration) FROM sessions WHERE session_duration > 180;.
2. Session Duration Bucketing: Group sessions into time bins (e.g., 300-second intervals) and count the number of sessions in each bin to understand session length distribution. This can be achieved with SELECT ROUND(session_duration / 300) * 300 AS session_bin, COUNT(*) AS session_count FROM sessions GROUP BY session_bin ORDER BY session_bin;.
3. Country-Specific Session Analysis: Compare session counts across different countries. This might involve self-joining a table of session counts per country to identify relationships or differences, such as SELECT t1.country AS country_a, t2.country AS country_b FROM (SELECT country, COUNT(*) AS session_count FROM sessions GROUP BY country) AS t1 JOIN (SELECT country, COUNT(*) AS session_count FROM sessions GROUP BY country) AS t2 ON t1.country != t2.country; (This example shows pairs of distinct countries, you'd adapt the join condition for specific comparisons).
