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".


Getting Data In

The best method for getting your data into DataShop depends on the state of your project.

If you are developing a course or study and have not yet collected data, then you probably want to log student-tutor transactions as they occur. The page Logging New Data describes a number of scenarios where you would log data from your course or study to DataShop.

If you are interested in viewing data from a course or study that has occurred in the past, then you probably want to import the existing data. The page Importing New Data describes the two main types of data that can be imported into DataShop: XML files and tab-delimited text files.
