Is there any way that I could find how many tables has statistics on them,and how many tables which doesn't have statistics on them.
I want to ensure all tables in the database has stats on them.there are 2k tables should I check manually whether this table exists in dba_tab_stats_history view.

query ALL_TABLES
It is trivial to differentiate between table which has statistics & table which has no statistics,
but how do you differentiate between table with goods, valid & current statistics & table with old, outdated, & incorrect statistics?

you should gather statistics on all tables (except SYS) on a regular schedule. On most of our databases above 8i, we do it at 5am every morning.
