The data are width-to-length ratios of beaded rectangles used by the Shoshoni Indians of America to decorate their leather goods. One might ask whether the golden rectangle (for which the width-to-length ratio is 0.618) can be considered an aesthetic standard for the Shoshonis just as it was for the Greeks and the Egyptians.
