Apply CSUQ to your test participants. You can use Excel template you used in the class. Statistical analysis: Submit raw data (task completion time & CSUQ) in the Test Data Excel File. The aim of this part is that you apply the statistical methods covered in the class. Therefore, only the statistical methods covered in the class must be used in this part. Other methods will not be graded. o Test Data . CSUQ Apply the tasks individually, and collect your task completion time data (in seconds). You are the "expert group" as you know the system. Statistically compare task completion time of your group (experts) and test participants (novice users). Comment on the results. Show all your calculations. Explain how you make your decision in hypothesis testing graphically. Calculate sub-factor mean values. Apply linear regression to CSUQ data and study the relationship between sub-factors and overall user satisfaction (CSUQ item-13.) Discuss significance of the models and strength of the relationships based on model parameters. Explain how you made your decisions. Show regression models. Propose improvements for the system based on user test and CSUQ findings, 1 SYSUSE INFOQUAL INTERQUAL overall 2 4.2 4.3 4.0 4.0 3 2.7 4.0 2.3 3.0 4 4.8 5.0 3.3 5.0 5 4.8 4.0 5.3 5.0 6 4.0 4.3 3.7 4.01 7 4.0 4.3 4.0 3.0 81 3.2 4.0 4.3 4.0 9 3.8 4.3 4.0 5.0 10
