title: Deepening our Understanding on the use of Models and Code in Game Software Engineering: A Controlled Experiment in Unreal Engine: Replication Package

description: This folder contains the material of an experiment that compares MDD and Ccd in Unreal Engine Context.

The material in this folder* is organized in three subfolders: 01_EXPERIMENT, which contains the information used to run the experiment; 02_RESULTS, which contains the information collected in the experiment; and 03_STATISTICAL ANALYSIS, which contains the data set and the results of the statistical analysis performed. 

The documentation contained in each of these folders is described below:

01_EXPERIMENT 

11_ CdE_ApproveReport: pdf file of the Favorable report from the ethical and scientific committee regarding the execution of the experiment.

12_Forms&Exercises: This folder contains the Taks Sheet for each group and the Unreal project with each exercise to resolve.

13_SupportMaterial: This folder contains the support material that the subjects could use during the performance of the different tasks of the experiment.

14_SessionMaterial: This folder contains the material used by the instructors during the session, including the video tutorial.

15_CorrectionMaterial: This folder contains the solution to the tasks and the rubric to correct.

 

02_RESULTS            

201_DATASET: Data files containing the values of variables and factors necessary for conducting the statistical analysis proposed in the study. They are included in both IBM SPSS Statistics (.sav) and Microsoft Excel (.xlsx) formats.

202_BOXPLOTS-HISTOGRAMS: Files that contain the execution and results of the boxplots for all the variables and factors considered. They are included in both IBM SPSS Statistics (.spv) and PDF Reader (.pdf) formats.

203_DATASET_LMM: Files that contain the dataset that includes the residuals of LMM executions. They are included in both IBM SPSS Statistics (.sav) and PDF Reader (.xls) formats.

202_DEMOGRAPHIC: Excel file with the demographic results.

203_DESCRIPTIVES: Files that contain the values of the main descriptive statistics and the results of the normality tests that correspond to all the variables measured in the study: the response variables and the independent variables or factors. They are included in both IBM SPSS Statistics (.spv) and PDF Reader (.pdf) formats.

204_LMM: Files that contain the execution and results of the LMM Type III test of fixed effects with unstructured repeated covariance for all the variables in the study with different statistical models. The files also includes the normality test of the residuals of LMM executions. They are included in both IBM SPSS Statistics (.spv) and PDF Reader (.pdf) formats.

205_LMM_model selection: File that contain information of the statistical models used in the statistical analysis and the comparative.

206_ DESSCRIPTIVES COHEN: Files that include the computations executed to determine the effect size of the factors in all the dependent variables. It is are included in (.exe) format.

 

*Note: The documentation that appears in this folder contains texts in Spanish, since this is the language in which the experiment is executed.
