So there’s no point in zebra striping?
This experiment yielded no evidence that zebra striping consistently improves the accuracy or speed of tasks. This would seem to suggest that we shouldn’t bother with zebra striping anymore.
However, there are a few arguments against tossing zebra striping out altogether.
Firstly, in this study there was a subjective preference for striped tables over plain. My reading and discussions with others suggest a number of people find zebra-striped tables more aesthetically pleasing. If many users like zebra striping (and another large group aren’t fussed either way), then why not apply it?
Secondly, this was just one experiment, with one dataset. It is possible that the particular design of this experiment meant that zebra striping had little effect. In other cases, particularly when there is considerable space between columns and/or the user is required to scroll horizontally, a more pronounced effect may have been observed.
Finally, and perhaps most interestingly, a number of participants in the study spontaneously reported using their finger, on or over the computer screen, to follow down columns and across rows. Other participants used their mouse to highlight rows of interest. These people were, in effect, creating their own “temporary” zebra striping. So we may be reducing the burden on our users if we do the zebra striping for them.
