BLEVEL B-Tree level: depth of the index from its root block to its leaf blocks. A depth of 0 indicates that the root block and leaf block are the same.
LEAF_BLOCKS Number of leaf blocks in the index
DISTINCT_KEYS Number of distinct indexed values. For indexes that enforce UNIQUE and PRIMARY KEY constraints, this value is the same as the number of rows in the table (USER_TBLES.NUM_ROWS)
AVG_LEAF_ BLOCKS_PER_KEY Average number of leaf blocks in which each distinct value in the index appears. This statistic is rounded to the nearest integer. For indexes that enforce UNIQUE and PRIMARY KEY constraints, this value is always 1.

If its value is near the number of blocks, then the table is very well ordered. In such a case, the index entries in a single leaf block tend to point to rows in the same data blocks. If its value is near the number of rows, then the table is very randomly ordered. In such a case, it is unlikely that index entries in the same leaf block point to rows in the same data blocks.

LEAF_BLOCKS Number of leaf blocks in the index.
DISTINCT_KEYS Number of distinct indexed values. For indexes that enforce UNIQUE and PRIMARY KEY constraints, this value is the same as the number of rows in the table USER_TABLES.NUM_ROWS.
AVG_LEAF_BLOCKS_ PER_KEY Average number of leaf blocks in which each distinct value in the index appears. This statistic is rounded to the nearest integer. For indexes that enforce UNIQUE and PRIMARY KEY constraints, this value is always 1.
