Accessibility Statement

Stats for Scholars is committed to ensuring that our statistical tutorials and research tools are accessible to all users, including people with disabilities. We strive to conform to the Web Content Accessibility Guidelines (WCAG) 2.1 at the AA level.

What We Do

  • Keyboard navigation. The entire site is navigable using a keyboard, including the interactive decision tree, navigation menus, and all content pages.
  • Skip link. A "Skip to main content" link appears on focus at the top of every page, allowing keyboard users to bypass repetitive navigation.
  • Semantic HTML. We use proper heading hierarchy (h1 through h3), landmark elements (nav, main, article, aside, footer), and ARIA labels throughout the site.
  • Readable typography. Body text uses a minimum 1rem base size with 1.6 line height. All sizing uses relative units (rem) so the site respects your browser's font size settings.
  • Color contrast. Text and interactive elements are designed to meet WCAG AA contrast ratios against their backgrounds.
  • Focus indicators. All interactive elements display visible focus outlines for keyboard users.
  • Responsive design. The site adapts to all screen sizes from mobile phones to wide desktop monitors.
  • Math rendering. Statistical formulas are rendered using KaTeX with proper markup, and scrollable containers prevent horizontal overflow on small screens.
  • No autoplay. The site does not autoplay audio, video, or animations.

Known Limitations

  • Complex mathematical formulas rendered by KaTeX may not be fully accessible to all screen readers. We include contextual explanations alongside every formula.
  • Some older browsers may not fully support the <details> disclosure elements used for progressive content.
