Using the SOCIO Chatbot for UML Modelling: A Family of Experiments

Data Analysis

This folder consists of data obtained from the experiments and the materials we use for analysis. Here we provide the following documents:

• The folder “Class diagrams”. The class diagrams that realized by participants in three experiments.
• Code.R. The code we use to analyze the raw data of three experiments. With this code, we generate profile-plots, violin-plots, the summaries of descriptive statistics. 
• Familiarity Result.xlsx. The data that we obtained from the familiarity questionnaire.
• Raw Data.xlsx. The aggregation of the raw data from three experiments. 
• Task 1 diagram.png and Task 2 diagram.png. The two ideal class diagrams correspond to Task 1 and Task 2. To analyze the response variable effectiveness and the quality of class diagrams, we compare these two ideal class diagrams with the class diagram realized by participants.
• Which Variable Is Statistically Significant?. xlsx. To give a better understanding of the statistical significance of the three experiments to readers, we additionally provided the comparisons of statistical significance toward each metric of each response variable.

Experimental Design

This folder contains the original materials used in the experimental design process. Here we provide the following documents:

• Experiment Procedure.pdf. The experiment procedure is identical among the three experiments. Here we provide the experiment procedure in detail.
• Informed Consent.pdf. We require participants to sign the informed consent before the experiment, and the informed consent received by each participant is the same.
• The folder “Questionnaires”. This folder contains the familiarity questionnaire we used before the execution of each experiment (i.e., Familiarity Questionnaire.pdf), the SUS questionnaire for Task 1 (i.e., SUS Questionnaire_Task1.pdf) and the SUS questionnaire for Task 2 (i.e., SUS Questionnaire_Task2.pdf).
• The folder “Tasks”. This folder contains the contents of Task 1 (i.e., Task1.pdf) and Task 2 (i.e., Task2.pdf).
• The folder “Tutorial Slides”. This folder contains the slides we use to give the tutorials of the chatbot SOCIO (i.e., SOCIO Tutorial.pptx) and the web-based online tool Creately (i.e., CREATELY Tutorial.pptx)
