Big Idea: In this part of investigation 2 we had to compare our popularity of certain sports in our own classroom in comparison to the popularity of certain sports in the chart " Participation in Sports Activites" to see which sport compared to another sport was more popular in comparison by actual numbers and by percents.

Essential Question: How popular in comparison is one sport as oppesed to the other sport in popularity numbers?

Notes from class: Are the numbers in this data chart still accurate as they are today? One of the key words of this part of the investigation is unit rate because I feel it holds significant use to what this part is talking about. The sports we used and the sports in the chart are very different.

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.

1. 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 data.

1. The number for the class data chart is extreamly smaller than the numbers for he national survey. For the class data the percents are smaller than the national surey.

C. Write three statements comparing sports activities of all students in your class to those of 1. 12 to 17 year olds in the national survey and 2. 55 to 64 year olds in the national survey.

1. The 12-17 age group is not gender divided like the class survey. The two data charts have different activitites. 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 for boys and excercise walking are the most popular activities. 2.2 follow-up

1. Write a paragraph telling how your class data 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 surveyes 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 wiht smaller groups of people. They both compare people doing sports. The class data uses all sports but the national survey does not because camping is not a sport.

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

1. There are a lot more boys than girls in the class surveys. 2. Dodgeball is the lest popular sport among the girls. 3. Badmitton is more popular with boys.
