Doug and David areresearchers who examine youth health. Numerous recent studies have suggestedthat youth in the 10- to 15-year-old range are increasingly engaged in manyhours of video game playing, they are not active enough (as defined by at leastone 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 thatalthough students play a lot of video games they remain active and engage insufficient exercise. In their current study they asked children to keep a logand then to report for a given week the number of hours of video game playingand exercise that they engage in and also to report the number of dinners thattheir families eat together as a measure of family connection. They alsocollected gender and age as demographic data.1. Identify the levelof measurement for each of the following variables: Age (reported in years),Gender (reported as Female=1;  Male=2), Hours of video game playing inthe week (reported to the quarter hour), Exercise (reported to the quarterhour), and Dinners taken together as a family (0-7 dinners in the week). 2. Which is the best measure of central tendency (mean, median or mode) foreach variable? Calculate the best measures of central tendency for eachvariable. 3. Are there more girls or boys in the sample? On average, do youth in thesample spend more time playing video games or exercising? 4. How many boys are there in the sample? 5. What is the average number of hours spent playing video games? 6. What is the average age of participants? 7. What is the mode number of family dinners experienced by participants in thesample?
