Because equal access to materials is an important goal of Connexions, the authors, and the many adopters of this text, several features have been implemented in Collaborative Statistics in order to improve content accessibility for disabled users. Every module that makes up this textbook takes advantage of each of the following features:
Alt Text for Images
Images used in text include alt text properties. These brief descriptions of the visual information are provided for users with screen readers so that they can accurately interpret the meaning of the images. Descriptions are generally one to three sentences and describe the image in broad terms, adding specific details only when necessary.
Table Row and Column Headers
Tables used in this collection have been marked with row and column headers where applicable. These headers generally describe the data in that column or row, and can be used by screen readers to help the user orient herself when traversing a data table.
Table Summaries
Table summaries provide a high-level description of the data. Because the contents of the table are accessible, table summaries generally only describe the nature of the table structure as well as identifying any trends or patterns easily recognized by sighted users. These are not intended to be detailed descriptions of the data, but rather an abstract.
