Doug and David are researchers who examine youth health. Numerous recent studies have suggested that youth in the 10-15 year old range are increasingly engaged in many hours of video game playing, they are not active enough (as defined by at least one hour of exercise per day), and they are disconnected to their family units. However, in some of their own previous research Doug and David found that although students play a lot of video games they remain active and engage in sufficient exercise. In their current study they asked children to keep a log and then to report for a given week the number of hours of video game playing and exercise that they engage in and also to report the number of dinners that their families eat together as a measure of family connection. They also collected gender and age as demographic data. (data chart attached as Jpeg)

1. What are the measures of central tendency for female participants for playing video games and exercising?

2. What are the variance and standard deviation for female participants for playing video games and exercising?

3. What are the measures of central tendency for male participants for playing video games and exercising?

4. What are the variance and standard deviation for male participants for playing video games and exercising?

5. Develop a frequency polygon that compares male and female participants for playing video games and exercising. (This can be done using Excel or hand drawn take a picture and insert)

6. Summarize the findings comparing female to male habits of playing video games and exercising.
