Late policy: 5% of the total marks available for the assessment shall be deducted from the assessment mark for each working day after the submission date, up to a maximum of five working days

Risks:

Please read the coursework instructions and requirements carefully. Not following these instructions and requirements may result in loss of marks.

Plagiarism results in award of ZERO mark.

The formal procedure for submitting coursework at XJTLU is strictly followed. Submission link on

Learning Mall will be provided in due course. The submission timestamp on Learning Mall will be used to check late submission.

All students must download their file and check that it is viewable after submission. Documents may become corrupted during the uploading process (e.g. due to slow internet connections). However, students themselves are responsible for submitting a functional and correct file for assessments.

All submissions must be written in English; Any parts containing Chinese will not be considered for marking.

Overview

In this coursework, you are required to complete two tasks based on the given dataset and submit a compressed document (in .zip file) that includes two files:

1. Task1: An Excel file (in .xlsx file) containing your visualization and modeling process and results for the given dataset.

2. Task2: A report (in .pdf file) analyzing the visualization and modeling results.

The assignment must be submitted via Learning Mall Online to the correct drop box. Only electronic submission is accepted and no hard copy submission.

Task 1 (50 marks)

You are given a dataset of Boston Housing. This dataset contains information related to housing prices in the Boston area, consisting of 12 numerical features and one target variable (the median price of owner- occupied housing). The introduction to the specific numerical features can be found in the Appendix.docx file. You need to design and create your visualization and model based on the dataset. The visualization will show the impact of different features on the median price of owner-occupied housing (which is in the column in red font in the .xlsx file), while the model needs to consider multiple features to predict the median price of owner-occupied housing. Here are task specifications:

Target for visualization: You are asked to use excel to create a visualization that complete the following tasks

l Clean and preprocess the original dataset (9 marks).

l Show the impact of the Average number of rooms per dwelling on the median price of owner- occupied housing through appropriate tables and charts (5 marks).

l Show the impact of the Percentage of lower status of the population on the median price of owner-occupied housing through appropriate tables and charts (5 marks).

l Show the impact of the Proportion of residential land zoned for lots over 25,000 sq.ft. on the median price of owner-occupied housing through appropriate tables and charts (5 marks).

l Show the impact of the Per capital crime rate by town on the median price of owner-occupied housing through appropriate tables and charts (5 marks).

Target for model: You are asked to use excel to construct a model that can predict the median price of owner-occupied housing (which is in the column in red font in the .xlsx file) based on the different features of these houses. Your model needs to complete the following tasks

l Choose the appropriate independent variable for the appropriate model (8 marks).

l Strive for low Mean Square Error (MSE) as much as possible (8 marks).

l Use the trained model to output the median price of owner-occupied housing, and present a

table showing the Mean Squared Error (MSE) corresponding to different predicted value ranges (5 marks).

The submitted Excel file should include:

l The original dataset

l The dataset after data preprocessing

l All visualized tables and charts

l Summary output of the constructed model

Detailed Requirements:

l The formulas and functions used in data preprocessing needs to be retained in your .xlsx file. You need to demonstrate through formulas how the processed data was transformed step by step.

l Visual charts and tables need to be generated by Excel and remain in an editable state in your .xlsx file. Screenshots will not be accepted.

Additional notes:

l The use of add-ins that have not been mentioned in lecture is allowed, but it is necessary to refer the source and ensure that the add-ins is publicly available.

l It is allowed to use newly constructed features during the model constructing, but these features must be based on the original dataset, and the process of constructing the new features needs to be retained.

Task 2 (50 marks)

In this task, you need to write a report based on your visualization and modeling results.

Target for report: You are asked to write a report (in PDF) to analyze your visualization results and evaluate your model's prediction result, the report should consist of following contents:

l Analysis of each visualization table and chart (16 marks).

l Conclude which feature has the greatest impact on the median price of owner-occupied housing and provide corresponding evidence (6 marks).

l Evaluation of the fitness of the model (5 marks).

l Evaluation of the predicted results of different predicted value ranges of the model (5 marks).

l Elaborate on the potential of your predictions in commercial applications (10 marks).

l Discuss the limitations of the model and potential directions for improvement (8 marks).

The formatting requirements in the report:

l Font: Times new roman

l Font Size: 12pt

l Page limitation: 1

l Line Spacing: single space

l Spacing Before: 0pt

l Spacing After: 12pt

Notes:

l Newly created features can be included in the discussion

l You can evaluate your model by comparing different models

l Discussions on directions for improvement can include discussions on improving the dataset

l You may get marks deducted if your report has more than 1 page
