7 Reshaping Data
5 Click OK.
A new data table is created that looks like Figure 7.12. Notice that the yield and trial columns are
gone, and the data table has two new columns. The names of the new columns are the unique values
(1 and 2) from the original trial column. The values from the original yield column are now split
into the new columns named 1 and 2. Also, notice that the columns other than trial and yield are
exactly the same as they were in the original table.
Figure 7.12 New Table Created by Splitting yield Column by trial Column
The names of these new columns
are values from the trial column,
and the values in the new columns
are from the yield column.
You can rename the new columns so the names are meaningful. For example, you might rename
column 1 to yield (trial 1) and column 2 to yield (trial 2), as shown in Figure 7.13.
