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".

Step List

The step list table describes all problems in a dataset. It provides a detailed listing of problem hierarchy (the unit and section divisions that contain the problem) and composition (the steps that make up a problem). Rows in the step list table are ordered alphabetically by problem hierarchy, problem name, and problem step.

The column headings are described in detail below.

Problem Hierarchy
The curriculum location in which the problem appears. The depth of the hierarchy can vary between datasets. For example, some datasets specify only a unit and section curriculum, while others specify a module, unit, and section. In terms of the DataShop logging format, the "problem hierarchy" is the list of type - name values contained in the dataset level element of each context message. (See the context_message element in the Tutor Message guide for a description of how this data is logged).
Problem Name
The name of the problem.
Step Name
The name of the step within the problem, described as a interface selection and action. Multiple steps commonly appear within a problem.

To export the step list table:

  1. Click the Export Step List button. Your browser will prompt you to select a folder in which to save the file.
  2. Choose a location to save the file. The file is saved as a tab-delimited text file, which you can open in a spreadsheet editor.
