EOL:Website-sci name avg table head/qqq

This is seen only by admins, on a page reporting on searches. This string is used as the heading of a column of data: each row represents a single search term (ie 'tiger') and the data for this column represents the average number of 'hits' for that term for the scientific name of a page. It's an average because the results can vary each time the search term is searched for--we get new names and we mark old names as invalid.
