| Question | Answer |
|---|---|
| Any issue that directly leads to task failure. | High Severity |
| Giving partial points to participants in completing their tasks is under binary success. | False |
| Not everyone believes in severity ratings. | True |
| Ease of use gives participant a reference for good and bad design before performing a task. | False (Usability magnitude estimation) |
| Post-study ratings are the most common way to collect self-reported data. | True |
| Motion is one of the behaviors that need to have equipment while to capture. | True |
| It measures how effectively users are able to complete a given set of tasks. | Task success |
| One of the ways to analyze the usability issue is to count the frequency of unique issues. | True |
| It is one of the guidelines in rating scales to use both positive and negative statements. | True |
| Likert scale allows the participant to rate a statement based on the level of agreement he or she experienced. | True |
| Anyone who uses technology interacts with some type of interface to accomplish his or her goal. | True |
| In levels of success, the participant is either will complete a task successfully or not. | False |
| Task failure and error might look the same. | True |
| Low severity of user experience contributes but does not directly prevent failure. | False (It is medium) |
| The Likert scale involves presenting pairs of bipolar, or opposite, adjectives at either end of a series of scales. | False (it is semantic differential scale) |
| Post-task ratings are the most common way to collect self-reported data. | False (post-study) |
| Assessing a product by asking the participant on what you like most do is an example of ____________. | Open-ended |
| Validation comes after designing for the sampling technique. | True |
| We do not need to operationalize the identified phenomenon for human behavior. | |
| In collecting task time, we need to log the start and end time of performing a task. | True |
| Performance metrics are used to determine the magnitude of a specific usability issue. | True |
| Issues should be specific and actionable. | True |
| We can simply examine each issue and then categorize it into a type of issue. | True |
| Checking whether certain details stood out is an example of awareness and comprehension. | True |
| Checking whether certain details stood out is an example of awareness and usefulness. | False |
| It gives the participant a reference to the good and bad design before performing a task. | Usability magnitude estimation |
| Capturing brain signals allows us to understand cognitive behavior during interaction. | True |
| what tells true emotion of a person (nalimutan ko i-copy yung tanong mismo pero ito yung tinatanong) | micro expression |
| You should measure errors when an error will result in significant loss of efficiency. | True |
| Learnability measurement is important in a continuous learning setup. | True |
| Trials is used under what performance metrics. | Learnability |
| According to task bias, the nature of the prototype or product you are evaluating has a huge impact on your findings. | False |
| To avoid bias, the person collecting self-report should be different from the test monitor. | True |
| We cannot user self-report to assess specific attributes on the product. | False |
| Facial expression is an example of verbal behavior. | False |
| It is the amount of effort required to complete a task. | Efficiency |
| One of the issues in considering time data is when do you need to report all tasks or just the successful ones. | True |
| An error opportunity is basically a chance to make a mistake. | |
| Collecting a verbatim comment is to require the participant to provide a comment at the conclusion of each task. | Automated studies |
| It is good for examining the overall design or organization but not good for specifics. | Low Granularity |
| Collecting data after each task may help us determine problematic tasks and parts of the product. | Post-task |
| Semantic differential allows the participant to rate a statement based on the level of agreement he or she experienced. | False (Likert Scale) |
| Usually, we use a wearable devices to capture pressure. | True |
| Microexpressions are facial expressions. | True |
| To measure efficiency, we need to identify the actions to be measured. | True |
| Trial is a test of the performance, qualities, or suitability of someone or something. | True |
| Time-on-task is particularly important for products where tasks are performed repeatedly by the user. | True |
| Learnability is a test of the performance, qualities, or suitability of someone or something. | False (Trial) |
| Incorrect action on the part of the user. | Errors |
| Usability issues are used to improve the product. | True |
| Not seeing something that should be noticed is an example of an issue. | True |
| One of its disadvantages is that the observer must take notes. | Oral |
| We need to define the characteristics of being bored for us to tell if the participant exhibit this behavior. | True |
| The Wii balance board is used to detect our posture. | False (central gravity) |
| Supporting the user in completing a complex transaction. | Usability findings |
| A small impact on user experience with few users experiencing the problem will give us low severity ratings. | True |
| This type of post-task ratings assesses the participants whether how easy or difficult a task is in comparison to how they thought it is. | Expectation measure |
| Making a survey anonymous may avoid bias in self-reported metrics. | True |
| Sampling allows you to choose the number of your participant. | True |
| different moderators will also influence the issues that are observed. | True |
| in identifying behaviors, one must come up with a definition for it. | True |
| some usability professionals believe errors and usability issues are essentially the same thing. | True |
| another way to analyze usability issue is to get the number of issues per participant should decrease per design iteration. | True |
| these facial expressions are universal, meaning they occur on everyone around the world. | False |
| Self-reported measures are measures in which respondents are asked to report directly on their own behaviors, beliefs, attitudes, or intentions. | True |
