Select a Dataset

Use the Dataset tab to select, preview, and edit the data used for SALT operations. Choose from existing datasets or upload your own comma-separated value (CSV) data. When opening SALT from a WebAssign question, the dataset for that question is automatically selected.

Dataset Sources

Most SALT analyses require a dataset. SALT datasets are provided in one of three ways:

  • Existing datasets
  • Uploaded CSV datasets
  • Datasets provided by WebAssign questions

Each dataset is a table of values for selected variables.

Variable Types

Variables can be one of two types:

Categorical

Qualitative values that are used to organize or categorize data.

Examples include diagnostic codes, dates, or names of things or people.

Numerical

Quantitative values that are used as the basis for numerical analyses.

Examples include measurements, prices, or counts of things.
