Are boys better than girls at math?
The materials required for this science fair project:
- The math exam results of 100 boys and 100 girls age 17 years, from 10 schools
- A computer to help analyze the data
- A survey form
- Permission from the school administration to obtain and use the data
1. For this science fair project, the independent variable is the gender of the persons who sat for the math exam. The dependent variable is their performance. This is determined by totaling the results of a hundred boys and a hundred girls respectively, from each school, and dividing by these totals by 100, to obtain the average results for both boys and girls in each school. The constants (control variables) are the age of the students and the level of difficulty of the math paper.
2. Ten secondary co-ed schools are randomly selected to take part in this survey. The co-ed schools are selected because they have both boys and girls being instructed by the same teachers and sitting for the same math exam paper.
3. Letters are delivered to the 10 selected schools to obtain their permission from their principals to have access to the math exam result of their students. It is important that you obtain sample results from different schools, in order to properly test your hypothesis.
4. Once the permission is obtained, visit the schools to gather the test result data.
5. From the information gathered, the average results for each school is calculated as follows:
Average math results for boys = (Sum of results for 100 boys)/100
Average math results for girls = (Sum of results for 100 girls)/100
6. The average math results for the boys and girls are calculated for each school and recorded in the table given below.
