Accessibility Features 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 ImagesImages 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 HeadersTables 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 SummariesTable 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.Media ZIP DownloadUsers can download a ZIP file containing all images, handouts, and other media files from the Collaborative Statistics homepage. After extracting the ZIP file, open the mediafiles.html file to access every media file used throughout the textbook, organized by chapter and module. This feature allows users to manage media files directly from one location. For example, blind or visually impaired users with access to special printers can generate printouts with raised images that can be examined as the screen reader advances through the text.
