4/8     Is a study that surveyed only 20 people statiscally significant:
        http://www.nngroup.com/reports/pr
        I don't remember much statistics but I do remember something
        about needing 33 subjects at a minimum for this kind of thing.
        \_ You have not enough clue. Mine more clue.
        \_ Usability testing is a far different realm than statistical
           sampling.  Many usability tests have only 5 or 6 participants.
           Don't worry, the people in the Nielsen Norman group know far far
           more about usability testing & statistics than you could ever hope
           to - they've created many of the techniques and wrote the papers &
           books and designed the products to back them up.  (Much of the
           modern GUI is based on work Tog did at Apple to refine the original
           Xerox designs and millions of websites are based on Jakob Nielson's
           design strategies.)
                \_ Not the point of the question. I was trying to get at
                   why isn't statistical sampling typically used in usabliity
                   studies?  Just because usablility tests typically ask a small
                   number of people, it doesn't make it right or
                   statistically valid.  Sure cost is an issue but
                   that doesn't mean that you can just make conclusions
                   up after sampling a (usually) small number of people.
                   BTW, I know who Nielsen is. I used to sit across
                   the hall from him at one point. I asked the question because
                   it has always bugged me that he almost always
                   uses sample sizes smaller than seems right. After being
                   the subject once and seeing how my comments ended
                   up in the final report, I feel the whole process that
                   these experts have set up is questionable.

        have in order for the print to "look good".  There is a rule of
        thumb?  Like 6 megapixel is good for X size print.  10 megapixel

3/21    Browser Plug-In you must get: Ghostery. It gets rid of a bunch of
        ad trackers on a web site, resulting in really fast load times.
        For example, a typical media site will require 10-15 trackers
        (you know, those URLs that track your activities so they can

Also examples from many other websites which the test users mentioned as particularly good or bad based on their experience as journalists. The sites included: * Six big American corporations (Fidelity Investments, Merck, Philip Morris, Qwest Communications, Tyco, Wal-Mart) * Six multi-national corporations based in Europe (Benetton, BMW, Deutsche Bank, GlaxoSmithKline, Nokia, Vivendi Universal) * One small company (Hemscott) * Three high-tech start-ups (Pace Micro Technologies, SeeItFirst, Tellme) * Two government sites (United States Patent Office, State of Maine) While all sites had some good traits, such as interesting content or some good interface designs, every site also had significant usability problems. At some point in every single test session, journalists said that they would have to leave the site because it failed to deliver what they needed. On average, users were only able to complete 70% of simple test tasks such as finding financial info about a company or finding the telephone number of a PR representative. After having a difficult time on a site, one journalist said, "I would be reluctant to go back to the site.

To be honest, we can only recommend this if Web-based PR is one of your main job functions. For people who are less heavily engaged in designing online PR, there is no reason to spend time and money on the second edition if you have the first edition. The most important guidelines are included in the first edition and none of the findings in the first edition were invalidated in the second study. Here's a short comparison of the first and second editions: * Guidelines: increased from 32 to 75 * Page count: increased from 114 to 218 * Screenshots: increased from 62 to 149 * Sites tested: increased from 10 to 18 > Read 22 Jakob Nielsen's Alertbox about the second edition What You Get * Checklist of 75 specific design recommendations: review your website and its press room for these 75 items, and you will discover several things that need improvement. You might have the one perfect site in the world that does everything right, but the odds are against you. It is safest to score your design against a checklist of usability guidelines to make sure you don't do anything wrong. Learn from the users' comments and reactions to common design mistakes in the PR sections we tested. The business value of better PR depends on the company, but is usually substantially higher than the cost of this low-priced report. Consider how much money you spend on PR to pitch your company: isn't it worth spending a tiny fraction of this amount to ensure that journalists are treated well if they decide to follow up and visit your site? This report has important information for: * Anybody who is responsible for the design or content of the PR area of a website * PR professionals wishing to advise their clients on proper use of the Web * Executives in charge of communications strategy for a major corporate website Running a similar usability study yourself to collect comparative design lessons from a large number of websites around the world would cost more than $150,000 and several months of an experienced usability professional's time. Please help us continue publishing low-price reports by buying a site license if you have colleagues who will read the report. If you only need it for yourself, then that's obviously what the single-user license is for. If somebody "gives" you a copy, then please buy a download anyway to keep prices down in the future.
