Sample Selector

Sample Selector is a tool for creating and editing samples, or groups of data you compare across—they're not "samples" in the statistical sense, but more like filters.

By default, a single sample exists: "All Data". With the Sample Selector, you can create new samples to organize your data.

You can use samples to:

A sample is composed of one or more filters, specific conditions that narrow down your sample.

Creating a sample

DataShop interprets each filter after the first as an additional restriction on the data that is included in the sample. This is also known as a logical "AND". You can see the results of multiple filters in the sample preview as soon as all filters are "saved".

Files

From the Files tab, you can add or view the following types of files by clicking on the subtabs:

  • Papers
  • External Analyses
  • Files

Note: To add or modify files for a dataset, your account needs to be given permission by the project principal investigator (and data provider, if one exists). If you don't have such access already, find the name of the project on the private datasets page and click Request Access. Be sure to select the "edit" access type ("edit access (view access plus the ability to edit dataset metadata and add files)"). The status of your request will be shown on the Access Requests page.

What's appropriate here?

Below are some examples of files that may be useful to others and which subtab they should go on, but feel free to upload whatever might be useful for your research group or others performing secondary analyses.

  • A paper that references data in this dataset (Papers)
  • A file that provides a mapping from the DataShop anonymous user ID to the original user ID for each student, useful if you are an instructor or are trying to compare student performance on pencil-and-paper pre/posttests completed in a school (Files)
  • Audio/visual artifacts gathered during the course or study (Files)
  • Statistical analyses (eg, from R, SPSS) (External Analyses)
  • Other analysis artifacts (Files)
  • Scanned pre and posttests (Files)

  1. Select the Papers, External Analyses, or Files subtab.
  2. Click Upload
  3. Browse for and select the file or paper on your computer.
  4. Fill in the appropriate metadata.
  5. Click Upload

Note: For external analyses, if you upload your file in text format, other users can view the contents of that file in DataShop without needing to download it. The analysis title will appear as a link.

To view a file:

  • Click the link under the File Name column of the file you'd like to view. Depending on the file type and your browser settings, your browser will prompt you to open the file for viewing or save it to your computer.
  • For external analyses, if the file is a text file, you can click the title of the analysis to view its contents within DataShop.

To modify a file:

  1. Click the edit button (edit button) on the row of the file you'd like to edit. The text fields will become editable.
  2. Modify the text in any of the fields, then click Save.

To delete a file:
