A small percentage of Hum Map points are invalid or malformed. Here is one thing that people can do to find those bad points, or points that have formatting issues.
Point to the Hum Database at https://www.google.com/fusiontables/DataSource?docid=1EyjVZqUPpoXGQDa_cry9DqFaBVMOgEyq-3qo85bx#rows:id=1
Click on File, and then Download. Go with the default choices, and when the file is downloaded, open it in Excel, Open Office Spreadsheet, or Google Sheets.
You can now sort columns – by age, for example, which can reveal typos and nonsense answers. Sorting columns also reveals rows that have data placed into the wrong columns. You may also spot some dates that are not written correctly. Dates should be given as mm/dd/yyyy. For example, “04/25/2016”, not “April 25, 2016”.
Please email me at email@example.com with your concerns. Please refer to the timestamp and reported hum location.
