During my first PSDA project, I learnt how useful the concepts I'm learning in the subject are. The methods we are learning can be implemented to many things and can be used to analyze different sorts of data. In the 2nd project, we used other methods that allowed us to perform more types of tests on the data. The projects taught us how to determine the questions that we will test and how to classify the results that we get. The projects increased our mastery in the subject overall and taught us valuable skills that will be needed in the future.
