Average Monthly Calls Vrs Text Messages by Age Group_ZIGGS

This set of data shows calls vs texts by age groups in 2006-2008.

The typical U.S. mobile subscriber sends and receives more SMS text messages than telephone calls, according to research released by Nielsen Mobile. Nielsen tracks billing activity through an opt-in panel of more than 50,000 personally liable, postpaid U.S. mobile lines across the top four carriers, AT&T, Sprint Nextel, T-Mobile, and Verizon Wireless.

Based on the research and chart below, it is concluded that teens between the ages 13 to 17 ends the highest number of text messaging, sending and receiving an average of 1,742 text messages per month.  In comparison, teens only make an average of 231 mobile phone calls per month, during the same time period.

In the same scenario, adults above the age of 45years tend to make more phone calls than text messaging per month, during the same time perion.

It's also noticed that there is an outlier of 1742 average number of monthly text messaging, which is very extreme based on the othe numbers.

Overall, I will conclude by saying that while voice may be on the decline, data and app usage is on the rise in the current generation.

We want you to do these projects with raw data. This data was already summarized, so it is difficult (if not impossible) to get summary stats. Graphs are nice however.

I really appriciate how you added the pie charts to give the viewer more of an insight of the percentages, however with your histograms, I do think that you may could have made your bins slightly bigger like 75 instead of 50, so that it would be a little bit easier to read. Other than that, excellent job!
