The following applies primarily to the E-Prime summary task data (not trial-by-trial data).

In The HTAC Customized Data Export section, you can request either Uncleaned or Cleaned data.

  • The Uncleaned Data will include all summary scores that have been created by the scoring of the raw trial-by-trial data, but which have not been cleaned to exclude subjects that have invalid or incomplete data. If you don't agree with the cleaning rules outlined below, or want to test out new cleaning rules, you would select this option.
  • The Cleaned Data will include all summary scores for subjects with usable task data. Although you may conduct additional cleaning of the data (e.g., exclude outliers after examining the distribution of a given variable), these data do not include subjects that failed certain criteria, as outlined under each task description, here HTAC. If you want to download data that is ready for analysis, you would select this option -- although you should still go through and check the data.
