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

The general process for creating a sample is to:

The effect of multiple filters

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".

Citing DataShop and Datasets

You can find dataset-specific citation guidance on the Citation page (Dataset Info > Citation) in DataShop or in the text file included with each export of data. This information is taken from the Dataset Info fields "Acknowledgement for Secondary Analysis" and "Preferred Citation for Secondary Analysis", which are settable by researchers who have edit access to the dataset. General citation guidance is given below.

To cite the DataShop web application and repository:

Please include the following reference in your publication:

To cite a dataset for secondary analysis:

You can find dataset-specific citation guidance on the Citation page (Dataset Info > Citation) in DataShop.

A primary paper is an article published by the owner of the dataset containing their analysis. Many datasets will have such a paper attached to the dataset under the Files tab. If not, there is a dataset citation listed (with a DOI) that you should use., Contact us if you have any questions
