    "content": "I summarised all seven numeric columns from two profiling queries: step-1 for the six measures and step-2 for YEAR. Each query covers all 62,496 rows. The rendered blocks show the full numbers.\n\n**Overall pattern:** the volume measures (page views, unique views, entrances) are extremely right-skewed. The median is tiny, the mean is far larger, and the standard deviation is orders of magnitude above the median. A few giant pages dominate.\n\n- **PAGE VIEWS:** min 0, max 228,326,194, mean about 15,904, median 8, stddev about 1.34M. p25 is 1, p75 is 98 and p99 is about 64,542. Most pages get a handful of views, and a thin tail gets millions.\n- **UNIQUE VIEWS:** min 0, max 16,424,436, mean about 4,101, median 6, stddev about 111K. p75 is 60 and p99 is about 47,930. The shape is the same as page views, just smaller in scale.\n- **ENTRANCES:** min 0, max 227,064,076, mean about 10,237, median 50, stddev about 1.04M. p25 is 0 and p75 is 200, so at least a quarter of pages record no entrances.\n- **AVERAGE TIME ON PAGE (seconds):** min 0, max 2,794.26, mean about 55.1, median 20, stddev about 124.8. p25 is 5.25, p75 is 58.04 and p99 is about 607.5. It is right-skewed but far less extreme than the volume columns.\n- **BOUNCE RATE (%):** min 0, max 100, mean about 16.2, median 0, stddev about 29.9. p75 is 19.5 and p99 is 100. The distribution is bimodal: a large cluster at 0 and a smaller one at 100, so the mean describes few actual pages.\n- **EXIT RATE (%):** min 0, max 100, mean about 23.8, median 0.54, stddev about 33.9. p75 is 42.86 and p99 is 100. It has the same spike at 0 and at 100 as bounce rate, but is a bit less concentrated at zero.\n- **YEAR:** ranges from 2014 to 2024, mean about 2019.4, median 2019, stddev about 3.2. p25 is 2017 and p75 is 2023. The rows are fairly evenly spread across the period, with a slight lean toward recent years.\n\n**Takeaways**\n- Use medians and percentiles, not means, for the volume columns. For example, the mean page views of about 15.9K is roughly 2,000 times the median of 8.\n- The extreme maxima for page views and entrances (about 228M and 227M) likely come from a single large site. In the per-site profile (step-0), city.brla.gov averages about 1.78M page views per page, while most sites average under 10K.\n- The 0 and 100 values in bounce and exit rate probably come from low-traffic pages, where a single visit pushes the rate to an extreme. They should be read alongside volume."
