Calculates and stores the ranks of the input column.
In number, specify the column. Minitab assigns rank scores to the values in the column: 1 to the smallest value, 2 to the next smallest, and so on. Ties are assigned the average rank for that value. Missing values are left as missing. Ranked scores are stored in a column.
A manufacturer of plastic parts wants to rank her machines by the number of defective pieces they produce. She records the number of defective pieces produced by each machine in a week, then enters the expression RANK(C1) and stores the results in C3.
|Number of Defectives||Machine||Rank|
Some analyses use ranks instead of the raw data. For example, Minitab uses ranks in some nonparametric analyses.
