2. Survey instrument
   1. Referring to the “Survey instrument” used in this study, explain how this instrument was organised and name each section. [Max: 100 words]

4. Findings
   1. Referring to the section “Demographic variables in the use of self-checkout counters”, the authors have concluded that there is no difference in the use of self-checkout counters across different demographic segments. What evidence have they given to evidence this conclusion? [Max: 50 words]
   2. In the same section, the report for the chi-squared test against the variable “Age” reads “𝜒²(4) = 4.06, 𝑝 = 0.40, 𝜙 = 0.07”. What is “4” in this report and explain how it was calculated? [Max: 30 words]

 

1. Referring to the section “Evaluation of self-checkout counters”, an independent t-test was used to compare the average scores for all the measures between users and non-users. Explain what could be the reason that all the test results were found to be statistically significant but with moderate effect [Max: 50 words]

 

5. Conclusion and further research
