It is important to observe trends in the time series data in order to assess which model to apply when undertaking a forecast of data. In this regard, graphical presentations are usually recommended. Thus in this study, graphs are used to show the trends in the data gathered as has been recommended by other scholars for observing time series data (Anderson, et al., 2010). One of the objectives of this paper was to assess the measures of central tendency and measures of dispersion (spread). In this study, we use mean scores and median values to assess central tendency and standard deviation, minimum and maximum values to assess spread in the time series data. Therefore, this has been done for sales, costs, and profits of Yahoo Inc. for the period under review. These results are presented in table formats in Part II of this paper. There are many methods that can be used to forecast time series data such as the one in this study (Table 1). In our assessment of the task at hand and the limitation of resources, we conducted the forecast using regression analysis technique which we found to be appropriate for this study. There are a number of statistical software available for conducting forecasts of time series data (Evans, 2003). These include but are not limited to Excel, SPSS, Stata, Eviews, R, and Minitab. Again, due to resource limitations and our assessment of the task at hand, we use the Excel software to conduct the forecasting exercise in the present study.
