e-Statistics

This web site is designed to teach introductory statistical method courses, and interactive tools would allow students to begin with their own investigation immediately.

A dataset can be uploaded for a standard data format of JSON, CSV (comma-separated values), or TXT (delimited text data in which a space is used to separate each field). When you are ready, click the folder icon on the left and choose your dataset file in a folder. Then it will convert any of the above forms into CSV.

In order to take advantage of the interactive tools a dataset must be specified in advance. If you see a table displayed at this page you have it. Otherwise, you have to set it by "visiting" one of the on-site data collections under "Data in Statistical Studies", or by "uploading" a dataset as instructed at the folder icon.
