• The ratio of girl swimmers to boy swimmers in our class is 7:5 • 33% of girls in our class swim at least twice a year, while only 24%of boys in our class swim at least twice a year. • 33%of boys in our class play American football at least twice a year while only 9%of girls in our class play American football at least twice a year. • While the ratio of girl swimmers to boy swimmers in our class is 7:5, the national data ratio comparing the amount of female swimmers to male swimmers is 33,640:27,713 • While 70% of the girls in our class swim at least twice a year, only 28% of the Females in the national data swim twice a year. • While 24% of the boys in our class swim at least twice a year, 24% of the men in the national data also swim at least twice a year 1. 12 to 17 year olds in the national survey 2. 55 to 60 year olds in the national survey** • In our class data 57% of our class altogether swims at least twice a year, while in the national data for the 12-17 year old age group 51% of the age group altogether swims at least twice a year • In our class data 57% of our class altogether swims at least twice a year, while in the national data for the 55-60 year old age group only 13% of the age group altogether swims at least twice a year. • The ratio of girl swimmers to boy swimmers in our class is 7:5, the national data ratio for the 12-17 to the 55-60 age group is 10,874:2756 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 appears to be different from the national data, give reasons why you think your class is different. •** Our class data for E block 7th Grade Math was in some ways similar and in some ways different from the national data. One way that our class data is similar to the national data is that in both the surveys the percentage of female swimmers compared to the percentage of male swimmers is comparatively larger. Some ways that our class data is different from the national data are that, we have much less people in our survey, as the number of people in our class is much less than the number of people in the United States of America. Another way that our class data is different from the national data is that the sports we surveyed are different as the national data surveyed activities like fishing and exercise walking while we surveyed activities like American Football and Soccer. Also the people in our class are from all over the world and have many different interests and backgrounds, while the people in America are mostly all from the same place and all have mostly similar interests and backgrounds
