Tip

Scan the map for red dots and check the chart for spikes. Big jumps or drops are usually where the interesting questions live.

Source: The numbers above come straight from Houston Open Data.

A 311 request can't be created next year. A future date usually means someone typed the date wrong or a computer formatted it incorrectly.

Next step: Check for a typo or a time-zone/format bug at the source.

🚩 High · impossible negative
85% sure

A count or amount is negative where that should be impossible.

numeric_value -7
You can't have negative days to fix a pothole, or negative permits. A negative number here is a sign of a data-entry or calculation mistake.

Next step: Confirm whether negatives represent refunds/corrections or are simply errors.

🚩 Medium · missing value
90% sure

The field "reported_by" is empty in 33% of records.

reported_by 33% empty
Think of a class roster where most students never filled in their phone number. If "reported_by" is blank 33% of the time, we can't trust any total or map that depends on it.

Next step: Ask the owning department why this field is so often blank.

🚩 Medium · broken coordinates
85% sure

Coordinates are missing, 0/0, or outside the Houston area.

lat/lng 0, 0
A point at 0,0 sits in the ocean off Africa. If a Houston event maps there, the location data is broken and the map will mislead people.

Next step: Re-geocode the address or drop the broken point from maps.
