Examples of hotel functions include setting daily room rates, attracting events (meetings, conferences, etc.), managing hotel material, etc. For each function, specify what data you would need to help you manage the function better, how you would analyze the data (using one or more of the descriptive techniques), what type of data individual variables represent (e.g., interval), and how you would tabulate or graph the data you collected for each function. For example, to set daily room prices, you can use historical sales data to compute average daily prices, a measure of dispersion to estimate up-and-down volatility, and histograms to graphically illustrate occupancy rates associated with different price levels. Your description of each of the three operational functions should include a clear specification of the function (e.g., setting daily room prices), a description of the data source (e.g., historical sales data), the data type, a specific descriptive technique to convert data into information pertinent to each function, and a description of tabular and graphical results, including examples generated using a Microsoft Excel spreadsheet.
