The number of violent crimes looks something like this: Click on Data Analysis option under Analysis section as shown in the below screenshot. Sorted data for Age: 3, 7, 8, 13, 22, 22, 22, 26, 26, 28, 30, 37 How Does Data Smoothing Work? Is there a daily trend in the arrival delays? In contrast, what does the figure below tell you about whether positive tests are currently up or down? This makes it both lightweight and flexible. However, in 2006 and 2007, it experienced 44 due to an experimental reporting requirement by the university's public safety team.
