The raw dataset contains numeric values for the categorical variables which might not be intuitive when used for analysis, the numbers are coded according to the document provided in UCI, values which could not be classified in the categories provided are coded as unknown. The age of the faculty members and their years of experience are binned into groups, age and years experience are categorised into a defined range.
2. Addition columns Question Type and Full Question are added to the dataset to allow for visualization in Tableau.
