Q101.
In the icon design experiment, what are the main dependent variables being measured?

a.

The order of presentation of icon conditions.

b.

The number of participants in each group.

c.

The variation in learning speed between participants.

d.

The time taken to complete the task and the number of errors made.

Discuss
Answer: (d).The time taken to complete the task and the number of errors made. Explanation:The main dependent variables in this experiment are the time taken to complete the task and the number of errors made during the task using both natural and abstract icons.
Q102.
Why is a within-subjects design chosen for the icon design experiment?

a.

To reduce the number of participants required.

b.

To observe how participants interact with the icons in their natural environment.

c.

To control variations in learning style between participants.

d.

To avoid transfer of learning effects.

Discuss
Answer: (c).To control variations in learning style between participants. Explanation:A within-subjects design is chosen to control variations in learning style between participants and to minimize the effects of individual differences on the results.
Q103.
What is the purpose of varying the placement of icons within the blocks on each presentation?

a.

To observe how participants interact with the icons in their natural environment.

b.

To ensure that participants have prior knowledge of icon placement.

c.

To minimize learning effects due to icon position.

d.

To increase the difficulty of the selection task.

Discuss
Answer: (c).To minimize learning effects due to icon position. Explanation:Varying the placement of icons within the blocks on each presentation helps minimize learning effects due to icon position, ensuring that participants are not simply memorizing icon locations.
Q104.
What statistical test is used to analyze the differences between completion times for natural and abstract icons?

a.

Student's t test.

b.

Chi-squared test.

c.

Analysis of variance (ANOVA).

d.

Pearson correlation.

Discuss
Answer: (a).Student's t test. Explanation:Student's t test is used to analyze the differences between completion times for the two conditions (natural and abstract icons).
Q105.
Why is the standard error of the difference (s.e.d.) calculated in the analysis of the results?

a.

To determine the number of participants in each group.

b.

To measure the expected variability of the difference between the means.

c.

To calculate the standard deviation of the data.

d.

To compare the means of the dependent variables.

Discuss
Answer: (b).To measure the expected variability of the difference between the means. Explanation:The standard error of the difference (s.e.d.) is calculated to measure the expected variability of the difference between the means and assess whether the observed difference is statistically significant.
Q106.
What is one of the challenges when conducting experimental studies involving groups compared to single-user experiments?

a.

Group experiments are generally less time-consuming.

b.

Group experiments are less prone to technical difficulties.

c.

Group experiments require a smaller number of participants.

d.

Group experiments often require more participants and time.

Discuss
Answer: (d).Group experiments often require more participants and time. Explanation:Group experiments typically require more participants and time compared to single-user experiments due to the complexities of group dynamics and interactions.
Q107.
Why might arranging suitable time slots for group experiments be challenging?

a.

Participants in group experiments are often not available.

b.

Group experiments tend to be shorter, creating scheduling difficulties.

c.

Group experiments usually involve fewer participants.

d.

Equipment availability and participants' schedules need to align.

Discuss
Answer: (d).Equipment availability and participants' schedules need to align. Explanation:Scheduling group experiments can be challenging because it requires coordinating the availability of both participants and equipment, which may include multiple workstations.
Q108.
What factor influences the choice of experimental tasks for group studies of groupware systems?

a.

The familiarity of participants with the equipment.

b.

The ease of performing the task without using the groupware system.

c.

The number of participants involved in the experiment.

d.

The technical complexity of the groupware system.

Discuss
Answer: (b).The ease of performing the task without using the groupware system. Explanation:The choice of experimental tasks for group studies of groupware systems is influenced by the need to encourage active cooperation and ensure that the groupware system is utilized. Tasks should ideally require the use of the groupware system to achieve their goals.
Q109.
What kind of tasks are often used in group experiments to encourage active cooperation and consensus-building?

a.

Tasks that involve individual creative thinking.

b.

Tasks that require participants to work independently.

c.

Structured tasks with clear step-by-step instructions.

d.

Creative tasks that require participants to reach agreement.

Discuss
Answer: (d).Creative tasks that require participants to reach agreement. Explanation:Creative tasks that require participants to reach agreement and work together to achieve a common goal are often used in group experiments to encourage active cooperation and consensus-building.
Q110.
In the context of group experiments, what might be a challenge when interpreting results involving a small number of participant groups?

a.

The lack of technical infrastructure.

b.

The inability to conduct statistical analyses.

c.

Difficulty in achieving participant consensus.

d.

The limited generalizability of results.

Discuss
Answer: (d).The limited generalizability of results. Explanation:One challenge in interpreting results of group experiments involving a small number of participant groups is that the limited number of groups might impact the generalizability of the findings and the statistical validity of the results.
