How to use data analysis in excel for qmb class

Since the current data set is only a sample of a population some crucial properties of sample statistics have to be taken into account before starting with the report. Finally, the researcher will predict future quantity of long-distance calls for the upcoming four quarters in order to support International Bell Communications in network capacity planning as well as in revenue forecasts, for instance. Second, regression analyses estimate the validity of a modeled relationship between the dependent and the independent variables. First, a general description of the data set will be presented, including the sort of variables, the characteristics of the observations, and the peculiarities in the distribution. There are three major parts in this report. However, the predictor variables of вЂњQuarterвЂќ, вЂњPriceвЂќ, and вЂњPerincвЂќ seem fairly reasonable influences on the number of long-distance calls, in general. Thus, the data has not been personally collected and hence the author of this report can not personally guarantee for the quality of the data set. The present data set was provided by the professor of the QMB class. The dependent variable is вЂњQuantityвЂќ вЂ“ the number of long-distance phone calls. The independent respectively predictor variables are вЂњQuarterвЂќ, вЂњPriceвЂќ (price charged for long-distance calls in US$), and вЂњPerincвЂќ (reflecting the local average personal income in US$). Four variables are provided in the вЂњIbellвЂќ data set three independent variables and one dependent (also called response) variable. based company International Bell Communications (Ibell) that owns and operates direct routes through-out the world (International Bell Communications, 2008). The вЂњIbellвЂќ data set is related to the U.S. The scope of the current project is to analyze a data set вЂњIbellвЂќ of phone calls and to predict future quantity of phone calls based on a regression analysis. With regards to business administration, modern business statistics can be used to influence decision making in finance, marketing or production, for instance. In many areas like science or economics, for example, statistical analyses are used to support assumptions and to predict future data. Statistical analyses are very important today.
