When I meet other runners a commonly asked question is "How many miles do you run a week?" This is a question I have not been able to answer, I have had no way to measure and track my weekly mileage. The number of miles a runner should run is often based on the distance for which they are training. Even given those guidelines, the optimal mileage for a runner will vary with the individual. While running has health and fitness benefits, some research has suggested that there is such a thing as too much mileage. While the threshold is still not determined, the threshold is currently thought to be somewhere around or above twenty miles per week.
In October 2014 I acquired my first GPS equipped cell phone. Using the Google My Tracks app I could, for the first time, run, juggle, and track my distance. Using the data recorded by My Tracks, I can calculate my outdoor running mileage for the first 16 weeks of 2015.

I. Basic statistics for a single variable
Course student learning outcome one: Students will be able to perform basic statistical calculations for a single variable up to and including graphical analysis, confidence intervals, hypothesis testing against an expected value, and testing two samples for a difference of means.

III. Open data exploration and data analysis
Course student learning outcome three: Students will be able to engage in data exploration and analysis using appropriate statistical techniques including numeric calculations, graphical approaches, and tests.
In 2014 I was aware for the first time that my weekly mileage was low for a runner. I wanted to improve my weekly mileage in 2015. The following data compares the mileage for the last 16 weeks of 2014 to the first 16 weeks of 2015.

Provide numeric statistical support for the answers to the following questions. Use the single blank to write up your answers to the questions including the statistical support for your answers.
Do not simply write down any and all statistics you have ever learned. Answer the questions and then cite the specific statistic, statistics, or charts that support that answer. When citing a statistic or statistics, include both the name of the statistic and the numeric value.
