# Scientific Questionnaire Report

## Hypothesis

If you are a boy, you carry more items in your backpack than that of a girl.

## Parts Of The Experiment

Dependent variable- The amount of heavy items in the backpack

Independent variable – Gender

Control – none

Experimental group- The High School Students

Two Factors held constant- One factor is the data being taken into consideration. This means that heavy items such as textbooks, full water bottles, Ipad and Laptop are only counted as heavy items while anything else apart from that in this list (such as a ball or shoes) aren't counted though they may be heavy. Another factor that is kept constant is the backpacks. This means that only heavy items are counted in the student's backpack which excludes gym bags, things in hand carry or anything that isn't in the student's backpack.

## Analysis

Women carry more items in their backpack than that of girls. Boys don't carry more items in their backpack than girls. The results after 13 boys and 13 girls answered the questionarre were not expected. The average number of items in a backpack for boys was 7.38 and for girls was 8.23. Boys don't take that many stuff because they don't want to have a heavy backpack and they mostly use technology for all their books and materials. Girls like to use books and stay as the old fashioned way. A study shows that carrying many items can cause many problems and that students should only carry up to 15% of their own weight in their backpack. I was very shocked that girls would carry more items in their backpack than that of girls.

## Conclusion

The hypothesis that boys carry more items in their backpack than that of girls was proven wrong. The data given proved that girls carry more items in their backpack than that of boys.

## Sources Of Error

There are several factors to take into consideration given that ANYTHING could be in a student's backpack. One fallacy in this experiment is fixed data. This means that only certain items in this experiment are considered heavy and counted while other things such as binders or stacks of paper aren't counted though they may be heavy. It is possible that the students could have heavy items such as a laptop or an ipad but not in their backpack. These items could've been elsewhere in their lockers or at home. They may have these items but don't necessarily carry it with them. This fallacy also explains that the data collected today may be different tomorrow because it is subjective. It could be possible that one student brought this laptop today because he/she needed to do work at school and not need to bring it the next day. This data, if collected today, will differ tomorrow because everyone is different and is affected by different external and internal factors.
