The story about Xcel Energy customers losing power in the Twin Cities metro area uses numbers in varying ways.
In the Star Tribune article, the numbers show the readers how many customers of Xcel were out of power, how many crews they have out to fix this damage, and how many different repair jobs that needed to be done. In the Fox 9 News article, it shows basically the same thing as the Star Tribune article, but adds another element to the story by showing how dangerous the storm was when it reported on the number of car accidents and injuries sustained during the storm.
The amount of statistics and numbers used in the story wasn't an overwhelming amount, but the number of people without power was an overwhelming number because obviously that is a significant amount of people, making this story appearing in the national news section on Google.
The reporter got their numbers from officials with Xcel Energy as well as officials with the State Patrol. I do not think the reporters could have used math to crunch out the numbers in the case of this story, because it would have been too many customers to count by themselves. It was easier for them, and made the story more effective to get the numbers right from the proper sources.
Both stories effectively told how badly this snow storm has impacted the metro area by using numbers in an efficient and relevant way.
