To select random rows

1. Select Rows > Row Selection > Select Randomly.

2. You can randomly select either a specific number of rows, or a proportion of the total number of rows:

Enter a whole number to select that number of rows.

Enter a value between 0 and 1 to select that proportion of rows.

For example, enter 10 to select 10 rows. Enter 0.1 to select 10% of the rows.

Select Rows > Row Selection > Invert Row Selection.

To select dominant rows

1. Select Rows > Row Selection > Select Dominant.

2. Choose the column(s) whose values you want to use to determine dominance.

3. Select the high or low values to dominate by for each column.

4. Click OK.

Note the following about dominant values and rows:

A value is dominant over another value if it is higher or lower (based on your specification).

The Select Dominant option selects each row that is not dominated by any other row. A row dominates another row only if all of its values are dominating the other row’s values.

The resultant set of rows is called the Pareto Frontier.

To save the current row selection in a new column

1. Select Rows > Row Selection > Name Selection in Column.

2. Type a column name.

3. Label the selected and deselected rows.

4. Click OK.

Tip: If you repeat this process after creating the new column and indicate the same column name, the original column is overwritten. Changes that you made in the data table to Selected or Unselected values are lost. Avoid overwriting those values by clearing the corresponding box in the Name Selection in Column window. For example, to avoid overwriting the Unselected values, make sure that the Unselected box is cleared.

To select excluded, hidden, or labeled rows

1. Select Rows > Row Selection.

2. Select from the following options:

Select Excluded

Select Hidden

Select Labeled

Note: For more information about excluded, hidden, or labeled rows, see Assign Characteristics to Rows and Columns.

To select rows that contain duplicate values

1. Select Rows > Row Selection > Select Duplicate Rows.

All duplicate rows except for the first are selected. If no columns are selected, duplicate rows will be selected using all the columns.

If columns are selected, duplicate values are found in the rows of those columns.

The match is case sensitive.
