2.11.2 Checking data condition accuracy and data
quality
Once the data has been merged to a master file, the file should be checked to verify the data it
contains, and that the values are within expected ranges. Rather than a checking of the logging
of variables (i.e., this would have been done prior to data collection), the checking at this point is
more in reference to the completeness and appropriateness of the data, the experimenter’s
assignment of subject numbers, and assignment of subjects to conditions. Particularly, if several
assistants are collecting data for one or more experiments, it is easy to mistakenly assign the
same subject number to several subjects, or to fail to assign subjects to a particular condition. E-
DataAid is the application within E-Prime, which allows the examination and modification of data
files.
2.11.2.1 Data editing
Data may be examined and edited using the E-DataAid application. To launch E-DataAid, click
the Start button, select Programs, and then E-Prime. From the E-Prime menu, select E-DataAid.
E-DataAid may also be launched from the Tools menu within E-Studio. The E-DataAid
application opens without loading a particular data file. A data file must be opened within E-
DataAid using the Open command in the File menu, or by clicking the Open tool button.
