Big Understanding: You are comparing the popularity of activities between two genders. You are also comparig the numbers between your class data and the data of the national survey data. You are also comparing which activities are more popular than others.

Essential question: Why is is that the older age group does one activity less than the other age group? Why does the younger age group do one activity more than the older aged group? For the present are these data records still as accurate?

Notes from class: Dodgeball is more enjoyed by boys than it is by girl. Becuase there are more boys than girls the gilrs popularity for sports is lower than it in all of the activities. Badmitton is the most popular activity. Most of the activitites amoung the boys are even for most of the activities and the same is also true for most of the activities for the girls. Most of their activities are tied and they unlike the boys do not have a favorite activity.

2.2

a. Look back at the three statements you wrote in part B of problem 2.1 comparing the numbers of male and female participants in the various activities. Now, make the same comparisons for boys and girls in your class.

For badmitton the female age group's number is 0.3% of the boys age group's number. For basketball the female age group's number is 0.38% of the boys age group's number. For dogeball the female age group's number is 0.13% of the number for the boys age group's number.

b. Compare the statements about your class data to the statements about the national survey.

The numbers for the class data cart are extremely smaller than the numbers for the national survey. For the class data the percents are smaller than the national survey. The activities for the class and national survey are also very different.

c. Writ three statements comparing sports activities of all students in your class to those of

1. 12 to 17 year olds in the national survey

2. 55 to 64 year olds in the national survey

1. The 12 to 17 age grou is not gender divided like the class survey. The two data carts have much different activities. Badmitton and swimming are the most popular activities.

2. Dodgeball for girls and bicycle riding are the least popular activities. Running for boys and fishing are highly valued, Badmitton and walking are the most popular activities.

2.2 follow-up

1. Write a paragraph telling how your class is like the national data and how it is different. For any ways in which your class data appears to be different from the national data, give reasons why you think your class is different.

Both of the surveys have boys and girls. They both deal with comparing numbers. The numbers for the class data are a lot smaller because the class data deals with smaller groups of people They both compare people doing sports. The class data uses all sports but the national survey does not becuase camping is not a sport.

2. In your class survey, you added several activities to the five listed in the nationalsurvey. Write at least three statements comparing the numbers of boys and girls in your class who participate in these activities.

There are a lot more boys than girls. Dodgeball is the leats popular sport among girls. Badmitton is the most popular sport with boys.
