Since this is a binary dataset, no indications of normal distribution were found on the data and therefore mainly non-parametric statistical methods were used to test the hypotheses. The main dependency analysis was then proceeded withKendal tau correlation and z-test for proportions statistical tests were used to answer the research questions.
