Assignment

Grade: 38/40

The main goal of the project was to create a report. The report had to contain clearly explained concepts of statistical data analysis applied to the existing dataset. There weren't restrictions for the selection of statistical methods, as long as they were applied to the appropriate context and covered in the course's curriculum. The report consists of the test cases selected from the recommended list of test cases provided by faculty personnel or cases made up by team members. One of the requirements was that the R language had to be used to analyze the data and generate the report.

The project's grade depended on the quality of the report and oral examination done by faculty personnel which examined the knowledge of the theory of the methods used (why you may or may not use a particular test, assumptions for tests used, details of the statistical methods, etc.).

Dataset

The dataset includes answers to survey questions with grades in mathematics and Portuguese of two students high schools. Collecting data on student achievement in teaching is a prerequisite for analyzing and improving the quality of education system. Details of the dataset are located at pdfs/dataset_documentation.pdf
