 Task Instructions

Step 1 : Select a publicly available dataset from the internet. Alternatively, you can use the same dataset used for A1, provided it allows you to apply the below listed advanced analytical methods

Step 2 : Find out the issues that the selected data has and apply suitable steps to handle the issues and errors if any. Also transform the data variables if needed, to make it suitable for subsequent analysis (Note: Use power query editor and DAX expressions)

Step 3 : Analyse selected data using the selected tool and implement the advanced visualisation techniques. Creating meaningful visualisations that give you more visual insight into data.

Step 4 : Based on analysis using visualisation, identify important finding about that data.

Step 5 : Carefully identify your limitations.
