Book Details

1. Introduction to online usability methods a. What is online usability, and how it differs from traditional usability methods b. Examples of different types of online usability studiesc. Pros and cons of online and non-online methodsd. When to use (and not use) online methodse. Combining online studies with lab testingChapter 1 provides an overview to online usability testing. Special attention will be paid to how it differs from traditional usability methods (including remote testing). There will be an in-depth discussion of the pros and cons of online testing, and when to use and not use online methods. We will provide real-world examples to highlight the value of this method. We will also discuss ways to complement traditional usability testing with online testing. Our intention is that the reader will be in the position to determine if an online usability study is appropriate for their organization. 2. Planning your study a. Study goalsb. Budgets and timelinec. Technology options d. Participant recruiting and panels e. Sample sizef. Panel optionsg. Sampling strategyh. Study durationi. Participant compensationChapter 2 focuses on all the activities and decisions that need to be made place prior to actually putting the survey together. The first three activities (goals, budgets/timelines, and technology options) are all essential to accurately scope an online study. The next part of this chapter focuses on finding the right number of targeted participants. This includes a discussion of research panels, sample size determination, and sampling strategies. The chapter will conclude with a discussion of estimating study duration and participant compensation. 3. Designing your study a. Introducing the surveyb. Screener questions c. Starter questions d. Constructing Taskse. Post-task questions and metricsf. Post-session questions and metricsg. Branchingh. Progress indicators and navigationi. Speed trapsj. Question typesChapter 3 is devoted to developing the study design. The first half of the chapter (topics a through g) are the various sections that are typically included in an online usability study. For each section, we will review best practices and common pitfalls. We want to give the reader the confidence for putting together an effective online study. The last part of this chapter (topics h through k) deal with common techniques that are used in various parts of a study. They include topics such as branching, navigation, speed traps, and question types. 4. Launching your study a. Piloting and Validatingb. Timing the launchc. Phased launchesd. Monitoring resultsChapter 4 deals with issues around launching an online study. This includes all the activities that happen after a study has been developed until the final data are available. This chapter discusses how to set up a pilot test and validate the study, timing a launch to maximize participation and quality results, and phased launches. The chapter concludes with a discussion on how to monitor results. This includes both participation rates as well as data quality. 5. Data preparation a. Fraudulent participantsb. Consistency checksc. Data reliabilityd. Outlierse. Recoding variablesChapter 5 will help the reader prepare their data for the analysis stage. There some very important activities that need to take place prior to data analysis that must be done to ensure valid results. Topics in this chapter will include how to identify fraudulent participants, running consistency checks on the participant responses, and identifying outliers in the data that may need to be removed from the analysis. The chapter will conclude with a brief discussion of how to recode variables that will be most useful in the analysis stage. 6. Data analysis and presentation a. Verbatim responsesb. Task-based metricsc. Segmentation analysisd. Post-session analysise. Behavioral dataf. Combining datag. Identifying usability issuesh. Presentation tipsChapter 6 covers all the information the reader will need to know about how to analyze and present data derived from an online study. Each section of this chapter covers one type of data that are typically captured in an online study. Verbatim analysis focuses on how to derive meaningful and reliable findings from open-ended responses. Task-based metrics include success, completion times, and ease of use ratings. Segmentation analysis includes ways to identify how distinct groups performed and reacted differently. Post session analysis involves looking at metrics such as SUS scores, overall satisfaction and expectations, and ease of use ratings. Behavioral data analysis includes metrics such as clicks paths, page views, and time spent on each page. Combining data from more than one metric is a very important step in analysis. Methods for identifying usability issues from all the data will be described and examples given. This chapter will be very practically oriented, giving step-by-step direction on how to perform each type of analysis. Many examples will demonstrate different ways to present the results. 7. Building your own online study a. Approaches to creating your own online studyb. Presenting tasks and prototypesc. Capturing task completion statusd. Capturing task time datae. Capturing self-reported dataf. ExamplesChapter 7 shows readers how to create relatively simple online studies themselves. Approaches to presenting tasks and prototypes will be described, as will techniques for collecting task success, times, and various kinds of self-reported data, including rating scales, open-ended questions, and the System Usability Scale (SUS). While some examples of HTML and JavaScript will be shown, we will describe them in such a way that even someone new to those technologies could understand and use them. Complete examples will be shown that readers could easily adapt. Code samples will also be provided on a companion website.8. Online solutions a. Keynoteb. RelevantViewc. User Zoomd. MindCanvase. Survey Monkeyf. Opinion Labg. ACSIh. OthersChapter 8 reviews the common online tools that can be used for running online testing. While the ?Do-It-Yourself? reader may want to use the techniques described in Chapter 7, others may want to use a commercial tool like those described in this chapter. Most of the chapter will be devoted to those tools that used most often to collect behavioral data such as Keynote, Relevant View, and User Zoom. There will also be a discussion of online tools that do not collect performance data such as Survey Monkey, ACSI, and Opinion Lab. Comparisons of the tools, including what kinds of data can be collected with each, will be included. The chapter will conclude with a brief discussion of other possible solutions such as agencies that specialize in online testing. Readers will also be referred to our companion website to keep up with updates and emerging software solutions.9. Ten tips for a successful online study a. Planning for metricsb. Deciding on the right toolc. Choosing the right participantsd. Writing clear taskse. Piloting your studyf. Checking data g. Comparing to other data sourcesh. Being creative with the datai. Allow enough time for analysisj. Presenting only the top line resultsChapter 9 provides a summary of some of the key points made throughout the book. This summary will be in the form of the top ten tips that someone should know when conducting their own online study. These tips will be very practical in nature.
