Enter the variable’s new name. The new name must begin with a letter, must be composed of
only letters, numbers, periods, or underscores, must not exceed 80 characters, and must not
already be in use. After entering the new name, click the OK button to rename the variable. With
the exception of log-level names, the variable’s new name is considered an edit. Thus, the new
name appears in red, and E-DataAid writes an annotation to the file describing the renaming.
5.3.4.4 Add a Variable
It may be necessary to add a variable for additional coding of the data (e.g., post-processing of
verbal responses). Adding a variable to an E-DataAid file is akin to adding a column to the
spreadsheet. To add a variable, use E-DataAid’s Add Variable command on the Edit menu to
display the Add Variable dialog. Enter the new variable’s name. The new name must begin with
a letter, must contain only letters, numbers, periods, or underscores, must not exceed 80
characters, and must not already be in use. Select the variable’s level and data type (i.e., integer,
float, or string). Click the OK button to add the variable. By default, E-DataAid places the new
variable at the end (i.e., as the last column) of the spreadsheet.
Adding a variable is considered a modification of the data file. Thus, the new variable’s name
(Congruency) appears in red, and E-DataAid writes an annotation to the file in reference to the
action. E-DataAid automatically fills the cells in the new column with NULL. To enter values for
the cells in the new column, simply click in the first cell and type a value. Depending on the
defined level of the new variable, E-DataAid will fill in the values when appropriate (refer to
section 5.3.2.1 Collapse Levels for a description of the hierarchical nature of experiment data).
5.3.4.5 Undo Edits
E-DataAid allows the user to “undo,” or rollback, any edits made to the file from the time the file is
opened until it is closed. To undo the most recent edit, use E-DataAid’s Undo command on the
Edit menu. Undoing an edit also removes the annotation written to the file by E-DataAid.
