Why are my indexes being ignored?

Hi,

    I created an index on a table. The table has about 83,000 rows. The index is a simple index on one field, 35 different values of the index. I analyzed the table and I analyzed the index, trying it both with a histogram and without a histogram. No matter how I do it, it does a full table scan. Any ideas why? I know I can use a hint, but it seems to me that it ought to use the index.
