Question: Read the usability study posted at http://www.measuringu.com/blog/mobile-desktop.php.

1. The study compares mobile and desktop user experience. While the authors do not explicitly state their hypotheses, define a null (H ₀ ) and alternative hypothesis (H _A ) that captures a key aspect of this study. Briefly (i.e., in 1 sentence or so) explain why you chose these hypotheses.
2. Briefly (though substantively) critique the study.

In critiquing the study, consider the authors’ use of statistics. Does the study appear to have been designed well? For example, did the study use a random sample? Were the variables measured in a meaningful way? Do you suspect any "bias" in study results, based on how the study was designed? Alternatively, did the article provide enough detail for you to be able assess/critique the study? Explain your answer.

The article mentions significance and non-significance at a given significance level. Consider these results. Do the authors appear to draw reasonable statistical conclusions? Explain. Briefly comment on the practical usefulness (or meaningfulness) of the study results.

You’re also welcomed to briefly state recommendations on how the study could be improved.

Note: The maximum length of your answer is 1/3 page. I will stop reading beyond 1/3 page. Within that space, write something concrete that applies your knowledge gained in IT 403. There is flexibility in your response, as long as you include something substantive from Module 7 and provide a concrete assessment based on specific details from the article.
