OVERVIEW

For the continuous assessment you are required to conduct and report on a statistical analysis to investigate a question for a given dataset. The dataset is available for download from the UCI Machine Learning Repository (https://archive.ics.uci.edu/ml/datasets/student+performance) where you will find a description. It is also used in the following paper which also provides a dataset descriptor:

P. Cortez and A. Silva. Using Data Mining to Predict Secondary School Student Performance. In A. Brito and J. Teixeira Eds., Proceedings of 5th FUture BUsiness TEChnology Conference (FUBUTEC 2008) pp. 5-12, Porto, Portugal, April, 2008, EUROSIS, ISBN 978-9077381-39-7.

Please ensure that you include this citation in the report you submit. 统计分析代写

For the purposes of the CA for this module you should consider that this is training data only. The dataset does not contain data from sufficient years to be able to fully fit a model, but it does contain enough for use to build and assess the fit of an initial model.

For this part of the assignment you are required to identify a number of concepts for which variables  are included in the data (or for which you can derive measures from variables in the dataset), inspect  the relevant variables and report your findings including relevant descriptive statistics and visuals  and present the outcomes of preliminary exploratory analysis of correlation and difference. This part  of the assignment is worth 50% of the CA for module as marked out of 100%.
