Request Results
Once all of your participants have completed the experiment, you are going to want to download the results. In order to do so, go to the 'Results' link and use the dropdown to request the results for your experiment. Alternatively, use the 'Request Results' button in the experiment list or summary display.
Results page
Immediately, ROLEG goes to collect your results securely. This may take some time, depending on the size of your results. Once ROLEG finished collecting your results, you will be informed by email automatically. Using the download link in this email, or the download link now displayed in the Results page, you can download your results.
Download format
The download format is a ZIP containing among others a CSV file using a pipe character "|" as delimiter. You can read the CSV file with a statistical analysis program. For R, you can use the following command.
For DSL version 2, the results CSV has different columns and use a whitespace as delimiter instead.
experiment_data <- read.csv("path/to/example_experiment.csv", row.names=NULL, sep="|")
If your experiments made use of audio recording, then the downloaded ZIP file will also contain a folder with the audio files, referenced from the CSV file. Remember that the results of the first few participants may be from your own test runs of the experiment. You should remove these lines before analysis.
Warning
Your results are available for download for 72 hours following the request date. If you have not downloaded the results within this time, you must request them again.
Result columns
Your CSV file will include the following columns with rows specified per trial. Note that a selfpacedreading block generates multiple trials, one per stimulus.
Info
If you have created your experiment before July 2022, the column selectedOptions will consist of the selected option labels, instead of their identifier.
