Information
The activities in StatZing! Secondary October 2006 use time-series analysis to make forecasts from historical data. The web activities make use of other information gathered at a accommodation establishment to analyse potential earnings. They involve a practical application of expectation algebra and normal distribution. The results can be used to analyse the occupancy rates and income generation of a fictitious accommodation establishment.
Together, the web and newsletter activities show how a commercial accommodation business could use their historical data to analyse the service that they provide, and to be informed about possible trends and potential profits.
