= All_rows INDEX SKIP Scanidx_t3_combineIndex Fast Full ScanOracle performs an index fast full scan when the index itself contains all the columns specified in the query. The difference between index fast full scan and index full scan is that the index full scan uses a single block read operation, while the index fast full scan uses multiple blocks of read. This scan cannot be used to avoid sorting, because the block is read by an unordered number of read-more blocks.Select Queryid from History

, and the previous index block becomes a pointer to the new index block. This pointer contains the relative block address of the new index block (Relative block Address,rba) and the lowest index value in the associated leaf block. By this point, the height of the index will change to a 2,blevel value of 1.As the data in the table continues to grow, the index blocks are further split, the heights continue to grow, and eventually a tree structure is for

central measure of the mean value. A workaround for the mean is the truncated mean, which removes the maximum and minimum number of values and averages the remaining numbers.Memory number Mo median Md mean μ intercept mean TMWhat are the links between these center trend metricsThe answer depends on the degree of bias (skewness) of the dataThe important thing to remember is that we cannot confine ourselves to only one central trend metric. For some data
