1. Create an ARFF file by using a text editor for this dataset and open the ARFF file in Weka [ 4 marks].

1. Observe the summary data for the data set and the histograms for all attributes on the Preprocess tab page. Use the Visualize tab page to view the scatter plots between the variables of the data sets. Put a screenshot of the tab in your assignment [ 2 marks]

1. Apply the unsupervised Discretize filter to the Assignment-4 marks. Put a screenshot of the filter output in your assignment and make some remarks on the data [ 2 marks]

1. Practice filling in the missing values for all columns in the Viewer window in Weka both manually and by using filters. Put a screenshot of the filter outputs in your assignment and make comments on what values are suggested by WEKA for the missing values? [ 2 marks]

Rationale

These tasks aim to assess your progress towards:
be able to identify and analyse business requirements for the identification of patterns and trends in data sets;
be able to appraise the different approaches and categories of data mining problems;
be able to compare and evaluate output patterns;
be able to compare and evaluate appropriate techniques for detecting and evaluating patterns in a given data set;
be able to identify and evaluate the security, privacy and ethical implications in data mining;

Marking criteria

The grade you receive for this assessment as a whole is determined by the cumulative marks gained for each question.
