You will need to revisit the procedure necessary to install additional Excel features. The Data Analysis option should now appear when you select the Tools menu. The textbook reviews the basic procedures involved in utilizing the Data Analysis tool. As you will see, there are 19 data analysis tools available within Excel. I want to address one important point that is not included in your textbook.
Some analyses produce their results by using a formula.
In this case, when you change the data, the results are automatically updated. Other analyses simple store a value, rather than a formula. In these cases, updated data will not be reflected in your results. As you review the different analyses available, notice which ones store a formula versus a value. As the textbook chapter indicates, a PivotTable can be used to rearrange how data is displayed and to select different data sets.
