Modifying model measures
Now that there are more tables in the model, we are going to add an additional measure to perform quick calculations on data. The measure will use a simple DAX calculation since this recipe is focused on how to add or modify the model measures. The future chapters will focus on more advanced DAX calculations.
How to do it...
Open the Chapter 3_Model project in the Model.bim folder and make sure you are in Grid view.
Select the cell under Count_of_Crashes and in the fx bar add the following DAX formula to create Sum_of_Fatalities:
Sum_of_Fatalities:=SUM(Crash_Data[FATALITIES])
Then, hit Enter to create the calculation:
In the Properties window, enter Injury_Calculations in the Display Folder. Then, change the Format to Whole Number and change the Show Thousand Separator to True. Finally, add it to Description Total Number of Fatalities Recorded:
How it works...
In this recipe, we added a new measure to the existing model that calculates the total number of fatalities...
